Mycorrhizal Fungi For Hydroponics

 Mycorrhizal Fungi Benefits in Hydroponic Systems 

The mutual relationship between Mycorrhizal Fungi and plants is a true wonder of nature.  Mycorrhizal Fungi are thought to have been essential in bringing plants to land some 450 million years ago!  Across millennia, this relationship has evolved and formed the landscapes that surround us.  Mycorrhizal made the evolutionary leap from water to land.  It only makes sense, then, that Mycorrhizal Fungi for hydroponics can also enable this unique symbiosis.  Using the best mycorrhizal products, and quality inputs, a simple hydroponic setup can yield awesome results.

There is a lot of information out there on how Mycorrhizal Fungi benefits plants grown in soil.  If you want to read more about that, check out the Mycorrhizal knowledge here, here, and here. 

The bottom line is that adding Mycorrhizal to your grow can reduce the rate of pathogen attack, improve stress tolerance, and promote plant growth, yield, and quality.  This holds true if you are growing in soil or in Hydroponics.

What Does Mycorrhizal Fungi Do For Plants In Hydroponics?

  • Increases Nutrient Use Efficiency and Uptake
  • Provides Plant Stress Protection 
  • Improves Crop Quality and Yield
The majority of research on Mycorrhizal Fungi has focused on plants grown in soil.  Hydroponic growers can also greatly benefit from using Mycorrhizal in their grows.  Let’s break down the types of Hydroponic Systems you can use and why you should consider using Mycorrhizal in your next Hydroponics grow.

What are Hydroponics?

Hydroponics are most easily defined as a method of growing plants without soil, where the plants are maintained with a nutrient rich water solution.  There are many different ways that hydroponic stems can be setup:

Types of Hydroponic Growing Setups

  • Wicking Systems:

    The wick or passive system is an excellent model for cultivating indoor plants.  It is a self-feeding model that does not require a water pump. Water or nutrient solution in a reservoir is supplied through a wick or fibrous materials (typically nylon) that can absorb and transport water from the reservoir to the root area by capillary action. The wick system is rarely used commercially, but the system has been used in small-scale gardens, such as personal home or office gardens, to grow flowering plants because of its simplicity. Even though it effectively inhibits the diseases common to overwatering, the wick system is not suitable for large or long term plants, which need a larger amount of water than the wick can supply.

  • Deep Water Culture (DWC)

    Most modified hydroponic systems were originally derived from the water culture system. The DWC system is a simple model, composed of a reservoir, an air stone, a tubing system, an air pump, and a floating platform.  With improvement of aeration methods to keep dissolved oxygen, DWC was developed so that plants can be grown with roots constantly suspended in water. Unlike the wick system, it produces food actively.  A floating platform supports plants or pots in a reservoir, where the root parts are constantly immersed in the water or nutrient solution and oxygen is supplied by an air pump and air stone. For optimization of growing conditions, it is necessary to monitor the oxygen and nutrient concentrations, salinity, and pH.  Although all kinds of plants grow well in this system, large or long-term crops may not, and algae and molds can grow rapidly in the reservoir.

  • Nutrient Flow Technique (NFT)

    The nutrient film technique (NFT) system was generated in the 1960s to compensate for the weak points of the ebb and flow systems.  NFT systems can provide water and nutrient constantly and make oxygen-rich conditions by controlling flow and water depth.  Water, or a nutrient solution in a reservoir, circulates throughout the entire system.  It enters the growth tray via a water pump without a time control, and then constantly flows around the roots.  The solution is collected and reused, and the amount of water is controlled by the slope of the tray and the power of the water pump. However, the roots are susceptible to fungal infection because they are constantly immersed in water or nutrient solution.

  • Ebb & Flow (Flood & Drain)

    The ebb and flow system was one of the first commercial hydroponic systems.  It uses an automatic flood and drain watering technique, in which plants are flooded temporarily and periodically.  Application of various media around root area is the great strength in the system. The water or nutrient solution in the reservoir ascends to a growth tray via a water pump, accumulates to a certain level, and stays in the growth tray for a set amount of time, providing water and nutrients to the plants. After a predetermined time, the solution is drained back into the reservoir through a tubing system.  This circulation system requires continual observation to control the amount of water provided to the system.

    Although it is possible to grow many different kinds of plants and provide them with a large amount of water, root disease and growth of algae or molds may easily occur in this system; therefore, some modified ebb-flow systems include a filtration step or other method for sterilization of the water.

  • Aeroponic

    An aeroponic system enables even control over the root system delicately and does not require media.  Using a high pressure sprayer with a micro-inject nozzle, water or a nutrient solution is sprayed around the roots by a water pump and provides a highly oxygenated nutrient solution to plants. Supports maintain the pots or plants, the water or nutrient solution is in a mist form, and is supplied for a specified period using a special nozzle and an electronic timer.  Customizing the misting cycles to particular plants is important, because their roots are exposed to the air and can dry rapidly.  The mist can easily be affected by the outside temperature, which makes these systems difficult to operate under cold or frigid conditions.

    This system is rarely used commercially because the system is expensive for installation and maintenance as it needs frequent cleaning to prevent plant disease and clogging of spray heads.  Also, partial failure of the aeroponic systems may easily cause damage or kill plant.

  • Drip

The drip or drip irrigation system has been widely used in commercial systems for many years.  Water or a nutrient solution in the reservoir is delivered to each plant or pot using a pump with the amount of water for each plant adjusted by an electronic timer.  

The drip system is divided into two models, recovery and non-recovery, depending on the processing of the reused water or nutrient solution.  In the recovery system, the water or nutrient solution is collected and returned to the reservoir and then recirculated through the system.  This makes it more economical than the non-recovery model, but reusing the solutions may result in pH changes and growth of algae or mold in the reservoir or tubing system.  In the non-recovery drip system, the amount of water or nutrient solution needs to be frequently monitored in the reservoir to ensure that enough water or nutrient solution reaches the roots of the plants.  The system is also vulnerable to power outage causing stress or death to plants.

  • Window Farming

    Window farming is an emerging concept in urban agriculture for space-saving and enabling residents to grow vegetables and herbs all year-round in urban settings with an available window. The window farm system is generally a vertical hydroponic system constructed of simple household materials, including plastic bottles, a water reservoir, and a small scale water pump with tubing.  Water circulates through the system via an automatic drip configuration using a pump and an electronic timer.  The sun supplies natural light, although artificial light may be needed on cloudy days.

    The vertical windowfarm system requires much less space than traditional hydroponic systems and provides an alternative method for growing crops in urban environments.  This trend is expected to continue, as window farming needs low input, creates sustainable agriculture in urban areas, including food deserts, and is able to provide urban residents with fresh and healthy foods.

    Easy Compost Tea

Deep Water Culture (DWC) is a popular way that many growers get into hydroponics.  The systems are easy to set-up, scalable, and grow great plants when you get it right!  But can Mycorrhizae be used in DWC?  Absolutely!  As well as any other hydroponic setup… 
Now, let’s get to the roots of how a successful Hydroponic system should work.  And why you should use Mycorrhizal Fungi for Hydroponics.

Hydroponic Growing Best Practices

  • pH(5.5-6.7)
  • Oxygen/Aeration (fully aerobic) 6-8ppm
  • Clean Water:  Chlorine (dissipates)/Chloramine (more difficult to remove)
  • Temperature 65-75 deg. F)
  • Nutrient Concentration (up to 30% increased efficiency with mycorrhizal)
  • EC (Electrical Conductivity) 1.2-2.0
  • Resevoir/Water Changes Every Week

Common Growing Mediums for Hydroponics

  • Rockwool:  Shown to increase pathogen resistance in soilless systems
  • Coco Coir:  Substitute for peat, free of bacteria and most fungal spores, excellent water retention
  • Clay Pebbles:  Lightweight expanded clay aggregate (LECA) used frequently in hydroponics 
  • Gravel:  Inexpensive, easily cleaned, drains well, works best in continuous flow systems
  • Oasis Cubes:  Rigid, open-celled, sterile foam, easily irrigated

 

Why Should You Use Mycorrhizal Fungi in Hydroponics?

  • Faster Growth/Bigger Yields (constant access to nutrients)
  • No Weeds (no cultivating, watering, tilling, etc.)
  • Water Savings (re-cirulated water)
  • Can be Grown Indoors in a Small Area 
  • More Controlled Environment/Inputs for Better Quality and Production

Mycorrhizal Fungi plays a significant role in Hydroponics, just as it does for soil grown plants.

Common sense might argue that Mycorrhizal couldn’t work in a soilless growing system.  However, there is one significant factor that both soil grown and hydroponic systems share.  The rhizosphere, or root zone.  

When Mycorrhizal Fungi colonizes plants, they greatly increase the surface area of plant roots.  This colonization recruits bacteria, fungi, and many other microbes.  Think of it like an internet for plants.  The Mycorrhizal Network… 

Beneficial Bacteria, fungi, and microbes use this ecosystem for mutual benefit with the plant.  They get Carbon from the plant for energy, in exchange for chelating nutrients, protecting against pathogens, and improving stress tolerance.  

Just as in soil, this Mycorrhizal network forms around plant roots in hydroponic setups as well.  With some minor differences.  Because of the way hydroponics work, microbe concentrations decrease much faster than in soil.  For this reason, it is important to re-apply at every water change.  This is due to the fact that microbes will not reproduce as rapidly in hydroponics as compared to soil.  

Maintaining a healthy ecosystem in hydroponics is extremely important.  As fluctuations in nutrient load, aeration, temperature, etc. can invite pathogens and root rot (Fusarium, Pythium etc.).  The beauty of incorporating Mycorrhizal and beneficial microbes in hydroponics is that they help to regulate nutrient use efficiency, pathogen attack, and changes in environment.  Maintain an oxygen rich, heathy environment for your plants and enjoy increased plant health, production, and yields! 

An important note for using Mycorrhizal Fungi in Hydroponics:  Phosphorous greatly diminishes Mycorrhizal growth.  When plants go into their flower cycle, Phosphorous requirements increase greatly.  Therefore, Mycorrhizal application should stop approximately 2 weeks before flowering.  This allows your plants to transition into the flower cycle by focusing on acquiring the nutrients they need for maximum flower yields.

 

How long does it take for Mycorrhizae to Work?

Mycorrhizal Fungi can begin to colonize plant roots in as little as 1-2 days.  The most effective strains of Mycorrhizal begin colonization within one week.  The process of colonization continues, with noticeable results showing in as little as 30 days.  There are many factors that contribute to the time that a Mycorrhizal colony will show obvious plant benefits.  These include your growing setup, plant species (strain), environmental factors, and more.  

In Hydroponics, it is important to apply multiple doses of Mycorrhizal through the early stages of plant development.  This is partially due to the fact that in hydroponics there is frequent water movement and/or the suspension of roots in solution.  Therefore, its is ideal to inoculate at every water change to guarantee complete root colonization and Mycorrhizal benefit.

 

What is the Best Mycorrhizae for Hydroponics?

  • High Spore Counts (guaranteed analysis of propagules/spores)
  • Multiple/Diverse Species (effective strains maximize colonization success)
  • Value-added combinations of Beneficial Bacteria, Fungi, Amino Acids, Plant Extracts, etc. (A biodynamic root zone ecosystem)

A quality Mycorrhizal for Hydroponics requires a product that contains spore counts that will be high enough to actively colonize the largest volume of roots possible, in as short amount of time as possible, for best results.  Lower spore counts mean that colonization will be slower, and less complete.  Therefore the benefits that Mycorrhizal provide will occur more slowly.  

A high spore count, in combination with a diverse blend of species, is ideal for the fastest and most complete benefit from Mycorrhizal for your plants.  Higher spore counts mean that more roots will be inoculated.  And will expand the root zone faster.  A diverse mix of species will allow the best chance of colonization.  This is because every grow is different, plant requirements are different, and change over time.  Where one species may take a larger share of the rhizosphere than another.  Because of these changing plant needs, the specific species of Mycorrhizal can change throughout a plants life cycle.  This is due to many factors, including the stage of plant development (seedling/vegetative/flower), growing conditions, environmental factors, substrate (soil type) etc.

 

The symbiosis between plants and Mycorrhizal is complex.  Many studies have shown that combinations of multiple Mycorrhizal and Beneficial Bacterial species show greater benefit to plants.  Specifically, they create a better plant health and growth promoting environment.  

This is because a wide diversity of species have different lifestyles and functions that complement the needs of the plant through its life cycle.  Certain Mycorrhizal Strains dominate depending on the environment they are in.  The microbes and fungi that habitate the rhizosphere use the Mycorrhizal network to survive.  In return, they provide numerous benefits to plants colonized by Mycorrhizal:

  • Plant Growth Promotion
  • Protection Against Pathogens (performed in numerous ways)
  • Solubilization of Nutrients/Increased Nutrient Availability (Phosphorous, Nitrogen, etc.)
  • Organic Acid Production (assists in chelating nutrients)
  • Plant Hormone Production (Auxin & Cytokinin production for root/shoot production) 

Mycorrhizal Fungi For Hydroponics Grow Better Plants

It’s all about the root zone!

Sterile vs. Non-Sterile Growing Environments

Old school thought in hydroponics has been to keep as sterile an environment as possible.  In order to prevent contamination from pathogens, maintain nutrient uptake and optimal water quality (pH, EC, etc.).  The reality is it is almost impossible to maintain a completely sterile growing environment.  

Instead, a robust, diverse concentration of Mycorrhizae, Plant Growth Promoting Rhizobacteria, and Beneficials gives plants an environment to thrive, and produce monster yields!

The common practice of keeping hydroponic systems as sterile as possible has been perpetuated.  There is still a lot to learn about using Beneficial Fungi and Bacteria in Hydroponic systems.  Especially for crops like Cannabis.  Current research is showing that the addition of Mycorrhizal Fungi and Beneficial Bacteria into Hydro Systems can have many benefits in terms of crop quality, health, and yields.

These Biodynamic systems, just as in traditional systems, need to be highly regulated and well-managed.  With technology constantly evolving and automation entering into growing operations, there is a great opportunity to incorporate these ‘living soil’ practices into Hydroponics.  Just as in a living soil environment, where the science has shown there are many benefits for plant success, the rhizosphere of plants in Hydroponic grows can mimic nature.  And grow great plants.

How to Apply Mycorrhizal Fungi: A Beginners Guide

How to Use Mycorrhizae and Plant Biostimulants 

Granular or Soluble?

When using Mycorrhizal Fungi or other Plant Biostimulants, such as our GreenEden biologic amendments, proper application to the plant, soil, turf, etc. will guarantee maximized results.

When you apply Mycorrhizal Fungi, the aim is to make direct root contact.

 This holds true for granular or water soluble products; As the Mycorrhizae will form a natural symbiosis with the root mass.  This greatly expands your plants reach, and allows increased access to the water and nutrients it needs to thrive.  

There are advantages to using a granular or soluble inoculant depending on your situation and conditions.  It is best to keep it simple, and not overthink it. Unlike common fertilizers and synthetic chemicals, Mycorrhizal Fungi cannot damage your plants due to using too much or too often; Follow the product instructions for the best results.

Read on to learn how you can find the best option to boost your grow with Mycorrhizae and Plant Biostimulants

How to Apply Granular Mycorrhizae

Seeds

Seed banding is a technique where you apply Mycorrhizae into the planting hole or furrow prior to direct seeding.  Always keeping in mind proper planting depth, watering in, and seed germination care.  It is typically best to follow the directions on your seed packet.  Another way to inoculate seeds is to mix the Mycorrhizae within the seed packet itself.  This is also effective, however, the coverage may not be as complete.

Transplants/New Plantings

For new plantings, incorporating a granular product, such as EndoBoost Pro, can be accomplished in a number of ways.  The Mycorrhizae can be incorporated into your backfill or directly applied to the roots of the planting.  Direct root contact is essential for the best results, as it holds the best odds for colonization and success.  Simply sprinkle a small amount of Mycorrhizae onto the root ball prior to planting.  When using EndoBoost Pro, you will only need about 1/2 teaspoon for a one gallon transplant.

Strawberry Transplant

Soil Amendment

Incorporating Mycorrhizae into a soil blend or potting mix will also be effective, as you are bringing natural, beneficial fungi into your soil.  Most store bought, bagged soils are typically lacking these beneficials.  Mycorrhizae needs a root mass to colonize and survive;  And over time some of the dormant beneficials will begin to lose viability.  So it is important to be aware of product shelf life.  This generally begins after one year or more.

How often you apply Mycorrhizae is important in order to get the best plant establishment, and lessen transplant shock.  

Additional treatments of Mycorrhizae can be made every 10-14 days through final transplant;  And approximately 7 days prior to re-potting or transplanting.  This gives the Mycorrhizal Fungi time to colonize your plants root mass and ensure a successful grow.

Established Plants

Granular Mycorrhizae and Biostimulants are also beneficial to apply to established plants.  Cultivate and blend into soil and make sure to water in well.  Amend to the drip line cover well and/or mulch.  Mycorrhizae cannot survive when exposed to sunlight.

EndoBoost Pro Mycorrhizal Fungi

How to Apply Soluble Mycorrhizae

Seeds

Biopriming, or seed soaking is a technique where a solution of Mycorrhizal Fungi/Biostimulants are made for seeds to soak in.  The idea is that the Biostimulants adhere to the seeds and are established at planting.  Using a product like EndoBoost Hydro will inoculate your seeds with a diverse variety of beneficials.  Recommended soaking times vary, but typically 8-12 hours shows the best results.

Transplants/New Plantings

Mix a solution of Mycorrhizae with non-chlorinated water and add as a soil or root drench.  Taking care to water in well.  The key, once again, is to make direct root contact.  Follow application instructions for the proper concentration.  Similar to granular products, Mycorrhizae may be added every 10-14 days through plant establishment.  And ideally at least 7 days prior to transplanting.

Hydroponic

Mycorrhizae can be added directly to hydroponic systems.  Care needs to be taken on what filtration systems/mesh sizes are used in specific setups.  Many of these solutions, due to their ingredients, do not fully solubilize and need to be decanted, or mixed to an agitated (suspended) state.  For example, GreenEden’s EndoBoost Hydro can be added to systems that use a 250 micron filter or larger.  This allows the many powerful Biostimulants to be fully incorporated for the results you require.

Established Plantings

There are many ways that Mycorrhizae and Plant Biostimulants can be effective when added to established, newly planted, or distressed trees or plantings.

Soil Drench

A soil/root drench is effective on porous soils, when watered in well to ensure complete root contact.  This is especially effective for greenhouse or potted plants.

Injection

On compacted soils, or to ensure penetration to the roots mass, a soil injection can be used.  This can be as simple as using a stake to get down to the root zone, usually 6-8 inches deep is all you need.  Use a grid pattern out to the drip line for an even distribution.  Then pour the solution into the hole(s).  There are also commercial grade root injectors available;  These are used primarily by professional arborists or landscapers.

InoBoost Ultimate Compost Tea

Foliar

It is important to note that Mycorrhizae are not effective as a foliar spray.  Mycorrhizal Fungi colonizes plant roots.  On the other hand, Biostimulants such as Humic Acid, Sea Kelp, L-Amino Acids, and others have massive benefits when used as a foliar spray.

What To Know When Using Mycorrhizal Fungi

  • Direct root contact
  • Keep out of direct sunlight; In a cool, dark place
  • Use non-chlorinated water
  • Follow product instructions for awesome results

Mycorrhizae and Beneficial Bacteria Work Together for Your Plants Success

GreenEden Biostimulants take advantage of the natural relationship that occurs in healthy and productive soil ecosystems.  Beneficial Bacteria and Mycorrhizae form an essential component of living soils.  They work in combination to build soils and give plants the conditions they need to give you professional results; without synthetic chemicals or pesticides.

Simplify the Science

The takeaway when you are using Mycorrhizal Fungi in your grow is this:  Keep it simple, get to the roots, let nature do the work, and…

How Do Mycorrhizal Fungi Help Plants

What Does Mycorrhizae Do For Plants?

  • Increase Nutrient Use Efficiency and Uptake
  • Improve Plant Stress Tolerance
  • Boost Crop Quality and Yields

How does GreenEden Mycorrhizal Fungi help grow great plants?  The 7 strains of Mycorrhizal Fungi in our products were specifically chosen for the benefits they provide your plants.  Each one of these strains are scientifically proven to greatly expand the root zone of plants.  This helps your plants get established quickly, and obtain the water and nutrients they need to thrive. 

GreenEden Mycorrhizae colonize plants across a wide range of growing conditions, and soil types, maximizing plant potential and performance.  No matter what your growing setup is.

There are many studies that have shown that using a combination of multiple Mycorrhizal species perform better than using a single strain.  This is due in part to the fact that not all Mycorrhizal perform the same in different types of growing conditions, environments, and plant and soil types.  

When you use a quality, multiple species Mycorrhizal product you give your plants the best chance for success.

EndoBoost Pro Mycorrhizal Fungi

Meet the Fungi

A Mycorrhizal Combination to Boost Your Grow The Natural Way

  • Funneliformis mosseae:  One of the most prevelant Endomycorrhizal fungi that colonizes a wide range of plant species across most climates.  Known to colonize medicinal plants such as Cannabis.
  • Rhizophagus intraradices:  Widely distributed and common strain that colonizes a wide range of plant species across various growing conditions.  One of the best Mycorrhizal species for Cannabis. 
  • Rhizophagus fasciculatus :  Wide ranging species that effectively combats drought, salt, and other biotic and abiotic stresses.
  • Glomus dussi:  Complementary species that is known to help increase root and plant mass, yields, and pathogen resistance.
  • Rhizophagus clarus:  Common species that colonizes plants and shown to increase Nutrient use efficiency, yields, and phytochemical content.
  • Septoglomus deserticola:  Species prevalent in dry regions that improves plant stress tolerance and drought stress tolerance.
  • Glomus microaggregatum:  Prevalent in wide ranging environments that adapts easily to drought stress and other adverse conditions.

The Mycorrhizal listed above are Endomycorrhizae.  Endomycorrhizae colonize up to 85% of all plant families.  This includes most vegetables (not brassicas), landscape plants, high value crops like Cannabis, and others.

The diversity of Mycorrhizal in GreenEden EndoBoost products allows your plants to to ‘choose’ the species that gives it the largest possible benefit.  Research has shown that Mycorrhizal populations change over time due to many different factors.

Check out these links (here, here, and here) for more on how research has shown the benefits of inoculation with multiple Endomycorrhizal strains, and in combination with ‘helper bacteria’ that boost plant potential, phytochemical content, and yields.

Establishing healthy living soils with Endomycorrhizae is one secret to successful gardening.  This is especially crucial for high-value crops like Cannabis.  Inoculating your plants with a robust and diverse population of Mycorrhizal Fungi and beneficial microbes grow better plants.  This combination helps your plants to better deal with stress, gain nutrients and water efficiently, and obtain what they need to thrive.

Mycorrhizal Fungi and Associated Microbiota as Plant Biostimulants

What to Look for in the Best Mycorrhizal Fungi Products

Multiple Mycorrhizal Species

Some products include a combination of Endo and Ectomycorrhizae.  These products make sense to use if you want to treat multiple plant types.  Conifers (pine, spruce, fir, etc.), Oaks, and other tree species are colonized by Ectomycorrhizae.  While some other species are colonized by both Endo and Ectomycorrhizae.  

Choose your Mycorrhizal wisely depending on what you’re growing and read product labels.  Don’t be fooled by products that inflate their Mycorrhizal counts by adding Ectomycorrhizal strains that will not colonize most plant types.

Spore (Propagule) Counts

Mycorrhizal propagules are a combination of spores, hyphae (root hairs), and root fragments.  These propagules each have the ability to infect plant roots and begin to form a Mycorrhizal network.  Higher spore counts give your plants a better chance at colonization.  This allows you to use a smaller volume of product for successful inoculation of plant roots with Mycorrhizal.

Complimentary Ingredients

Living soils grow great plants 

Mycorrhizal Fungi do not work alone in building living soil.  The complimentary ingredients in GreenEden Inoculants work with the Mycorrhizal to help obtain the nutrients and beneficials your plants need for a successful grow.  

Plant Growth Promoting Bacteria, Beneficial Fungi, Humic Acids, Plant Extracts, Vitamins and Amino Acids.  These are the triggers that unlock untapped resources from your soil and give you the much sought after production and yields growers expect.  Read more about these Plant Biostimulants here.

The science behind Mycorrhizal Fungi is complex and the research is always evolving.  There are many things we still do not understand.  What is known is that a plants root zone is a complicated ecosystem.  And the colonization of the root zone by Mycorrhizal evolves and changes over time.  Plants communicate with this ecosystem and take what they need to survive and thrive.  This ‘Internet of Plants’ works as a system that benefits both plants and the organisms that live among them.  This is how Mycorrhizal Fungi help plants.

Why Are Mycorrhizae Important To Plants and Soil?

Living Soil


worm castings

What is the difference between dirt and soil?  And why do mycorrhizal fungi play such a critical role in developing natural, healthy, resilient plants and soil?  First, lets define the terms…

Dirt is made up from three main components: Sand, Silt, Clay.  Inert, lifeless particles.  Mineral fragments.  Basically a medium to host the diverse array of life that inhabits soil.  Merely one component in the composition of a living soil.

Soil is a combination of ‘dirt’, organic matter, liquid, and gases.  It is with these added materials that we begin to develop a living soil, also referred to as the Soil Food Web.  This diverse, complete habitat supports a vast array of fungi, bacteria, protozoa, worms, vertebrates, insects, and plants. All part of a living soil, and critical to maintaining a healthy overall environment.  These organisms contribute to this environment by allowing for increased plant nutrient supply and soil structure, protection from harmful parasites, reduction in erosion, salinity, and leaching of nutrients.

Mycorrhizal fungi are an integral part of this living soil environment.  They act as a foundational organism for the soil ecosystem.  Many studies have been conducted that show that the presence of mycorrhizae in soil has many benefits.

Almost all land plants form symbiotic associations with mycorrhizal fungi. These below‐ground fungi play a key role in terrestrial ecosystems as they regulate nutrient and carbon cycles, and influence soil structure and ecosystem multifunctionality. Up to 80% of plant N and P is provided by mycorrhizal fungi and many plant species depend on these symbionts for growth and survival<1>.

Vast networks of Mycorrhizae form in habitats that are undisturbed or managed sustainably.  These networks allow for the movement of water and nutrients amongst varying plant species.  The most prevalent of these fungi are the Endomycorrhizae, or Arbuscular Mycorrhizae (AM).

These fungi form mutualistic symbiosis with more than 85% of higher plant species. They play important roles in plant resource capture and nutrient cycling. The ability of AM fungi to enhance host plant uptake of relatively immobile nutrients, in particular phosphorus (P), and several micronutrients, has been the most recognized beneficial effect of mycorrhiza.  Arbuscular mycorrhizal fungi absorb inorganic P either from the soluble P pools in the soil, or from insoluble forms, such as, rock phosphates (RP). Recent studies show that the mycorrhizal fungus Glomus intraradices solubilized RP through localized alterations of pH and/or by the production of organic acid anions, that may act as chelating agents<2>.

In simpler terms, mycorrhizae make nutrients and micronutrients more readily available to plants.  By breaking down organic matter, chelating (bonding) nutrients from the soil, and improving water holding capacity, these fungi form the base of a living soil.  Allowing the soil to naturalize and build a healthy ecosystem.

Now for the catch…

Land management practices affect the formation of mycorrhizae. The number of mycorrhizal fungi in soil will decline in fallowed fields or in those planted to crops that do not form mycorrhizae. Frequent tillage may reduce mycorrhizal associations, and broad spectrum fungicides are toxic to mycorrhizal fungi. Very high levels of nitrogen or phosphorus fertilizer may reduce inoculation of roots. Some inoculums of mycorrhizal fungi are commercially available and can be added to the soil at planting time<3>.

Common, accepted practices have gone against what nature has intended.  Tillage, synthetic fertilizers and pesticides, topsoil stripping.  All of these affect soil structure and the overall soil ecosystem.

In order to build a natural, healthy, resilient soil ecosystem, an entirely different approach needs to be taken.  Minimal tillage (no till), mulching bare soil, use of natural/organic soil amendments,  and crop rotation practices need to be considered.  Thoughtful amendment of living soil ecosystems.  Mimic nature, build the soil, and see better results.

Simple Living Soil Recipe for Seed Starting

Easy Living Soils

Everyone that enjoys cooking or baking have their own go-to methods and hacks they rely on for success.  Growers are no different.  There are so many different ways to get to similar results.  We are going to focus on an easy and effective way to make a quality living soil seed starting mix on your own.  Just like baking a cake.  With only a handful of ingredients to get your plants off to a great start.

This mix is ideal for seed starting and an excellent base for creating a biodynamic growing system.  Incorporating the least amount of inputs and gaining the maximum benefit.  Using nature as your guide to grow great plants.

What is Living Soil?

A healthy living soil is a healthy ecosystem.  And a healthy soil ecosystem contains the elements that any other healthy ecosystem has.  DIVERSITY.  Living soils contain a multitude of beneficial bacteria, fungi, protozoa, nematodes, earthworms, and more.  These diverse organisms work synergistically to break down organic matter and nutrients that are made available to plants.  They also defend against soil pests and pathogens.  

Living Soils are made to be used biodynamically.  Re-amended and re-used over multiple growing cycles.  Using no-till methods assist in keeping the diversity of your living soil intact.  Living soils are complex systems where encouraging and maintaining a biological diversity of beneficial life is key.

This living soil mix is intended to get your plants established quickly, with reduced risk of plant loss or transplant shock.  Living soils let your plants gain nutrients and water more efficiently, using less fertilizer and water.  This simple, effective soil mix is something that any beginner or master grower can use for awesome results.

There are 4 key components to this living soil mix.  As we are just going for a seed germination mix, there are no additional nutrients added to start.  And of course you can add to and tweak it to your own preference.  We will list these individually, with options for whatever other input alternatives may be more readily available in your area.  

How to Create a Living Soil

Peat Moss/Coco Coir (1 Part or 1/2 part each – 40% of mix)

Peat and coco can be used individually or mixed together in equal parts.  They are the main ‘bulk’ of the soil, and have good water holding capacity.  It is important to water these in well prior to blending and planting.  Peat is ‘hydrophobic’, which means it is difficult to wet and sheds off water easily.  Where coco is ‘hydrophilic’, which means is can easily absorb water.  Blending these two inputs give you a quality base to start with.

 

Perlite/Pumice/Vermiculite (1 Part – 40% of mix)

We mix roughly equal parts of our ‘base’ peat/coco with one of or a combination of these.  Perlite, pumice etc. gives the soil good drainage and aeration.  Different regions have different ingredients available.  Vermiculite (shown below) is fairly common, and some areas may have something like rice hulls available.  The most important thing is to keep the ratio close to the peat mix or slightly less.  

Vermicast/Compost (15-20% of mix)

A quality compost is a key factor in this living soil mix.  Compost holds a great mix of plant available nutrients in a concentration that will not burn young plants when used in these smaller amounts.  There is also an abundance of microbial life in composts that hold other numerous benefits.  Just what we’re looking for in a living soil.  Studies have shown that vermicast (vermicompost) used in ratios no greater than 20% have many benefits in regards to seed germination and early plant development.  

EndoBoost Pro Granular Mycorrhizae (2% of mix – follow application instructions)

Living Soils are an ecosystem.  And we want the most healthy, productive, and effective ecosystem to grow great plants.  EndoBoost Pro helps create the conditions for that to happen.  Mycorrhizal Fungi to expand the root zone.  Beneficial Microbes for increased plant performance, soil health and protection.  With powerful Plant Biostimulants to feed your soil, and drive plant growth and yields.  Amendments for living soil that give you the best results with the least inputs and waste.

How to Mix Your Living Soil

Now that we have identified each individual part of the mix, they can be blended and watered in to complete the process.  The simple ratio of ingredients can be measured out to whatever quantity you need.  Nothing changes whether you are measuring by the gallon or yard.  Home gardeners looking to start their annual vegetable garden, for example, would be best served measuring by the gallon.  

For an example, we will mix 5 gallons of soil.  Use a tarp, mixing bucket, tray, or wheelbarrow.  Whatever you have on hand.  Add 2 gallon of peat moss for each 2 gallons of vermiculite, for example.  Water well and mix to the consistency of a damp sponge.  Estimate soil moisture by squeezing a handful of soil to see a firm consistency with no water actively dripping or flowing from your hand.  You would then add up to 20% of quality compost (no more than 1 gallon for this example).  Finally adding the EndoBoost Pro Mycorrhizal at the rate of to 2tbsp. per 5 gallons (1tsp. per gallon).

And there you have it!  5 gallons of a great living soil ready for your seeds.  

Seed Starting Basics

Now it is time to plant those seeds.  Ideally, you have your pre-moistened living soil blend ready to go.  Your solo cups, planting cells, or paper pots on hand.  And of course the seeds you want to plant.  The idea is to get the seeds into an environment where they can sprout and have room to grow.  Depending on the plant, you may need to transplant into a larger container before final transplant.  Either way, you want to minimize the disturbance to your seedling.  Therefore, use a proper sized container so you end up transplanting as few times as possible before the plant finds its home.  

You want to make sure that your living soil mix is secure and packed down into the container.  Firmly, but not so much that it ends up being a solid block.  Remember that we want our beneficial organisms and plants roots to be able to get the access to water and nutrients that they need.  An overly compacted soil will more than likely cause problems.  

Make sure to follow the directions on your seed packets and plant at the proper depth.  Certain plants are more fussy than others for germination.  The general rule of thumb is to plant at a depth 2-3 times the width of the seed.  Lightly cover the seeds and water in.  It is best to mist the plants as opposed to other harsher methods that may dislodge your seeds or damage seedlings.

Boost Your Grow The Natural Way

Keep soil moist, warm, and get the seedlings under supplemental light or a south-facing windowsill when they sprout.  Use this mix right through final transplant.  Keep your living soil vibrant and productive with waterings of a quality soluble Mycorrhizal Inoculant like EndoBoost Hydro, and follow up with InoBoost Easy Compost Tea in addition to your normal feeding program.  Look for increased plant performance, flowering, and yields.

EndoBoost Hydro Soluble Mycorrhizae

How To Grow The Best Plants Naturally With EndoBoost Hydro

What Is EndoBoost Hydro?

A Powerful, Soluble Microbial Biostimulant – With The Most Diverse, Concentrated, And Complete Nutrient Enhancing Formula – To Boost Your Grow The Natural Way! 

 EndoBoost Hydro has a supercharged blend of ingredients that naturally builds soil and benefits plants; and is guaranteed to boost your growth, yields and production.

Endomycorrhizal Fungi have evolved over hundreds of millions of years.  It has been theorized that mycorrhizae are a key reason that plants transitioned from sea to land.  85% of all plants form a symbiosis with Endomycorrhizae, where plants feed the fungi sugars from photosynthesis, and mycorrhizal colonize and extend plant roots to make water and nutrients more readily available to plants.

Mycorrhizal Fungi are essential to establishing healthy, productive plants.  They set the stage for explosive root growth, increased nutrient and water availability, and protect against pathogens.

Beneficial Bacteria act as the “probiotics” for plants.  A healthy, living soil needs a diversity of microbes to give your plants the essential nutrients they need to thrive; and create the conditions for strong, healthy, resilient plants and soil.

These Plant Growth Promoting Rhizobacteria (PGPR) break down organic matter and macro and micronutrients, induce plant growth hormones, increase nutrient availability, improve soil health, and defend against pathogens.

Humic Acids, Sea Kelp Extract, and Yucca Plant Extract are the Biostimulants (Biofertilizers) that feed your living soil.

Humic and Fulvic Acids are powerful chelators that increase nutrient uptake, boost microbial activity, increase drought tolerance, and improve soil structure.  They are formed through the breakdown of organic matter, and are sourced as leonardite.  Leonardite is found near lignite based coal deposits, and serve as the best natural source of humic substances; organic matter in its most pure form.

Sea Kelp Extract is a natural biofertilizer, with over 70 trace minerals and vitamins, growth hormones, enzymes, and proteins.  Seaweeds have been used as fertilizers for millennia; and aid in cell division, soil fertility, feed microbes, and enhance nutrient utilization.

Yucca Plant Extract is a natural surfactant.  It helps to break the surface tension of water, allowing for better soil infiltration.  This improves nutrient uptake and water holding capacity.  Yucca also protects against plant stress and reduces salt buildup in roots and soil.

Trichoderma Fungi are a truly unique and powerful biostimulant.  Like mycorrhizal, it colonizes the area around plant roots.  But unlike mycorrhizal, it can also survive away from plant roots for some time.  It works with other microbes through this colonization to promote plant growth, defend against root and plant pathogens, fixes nitrogen, and induces many plant growth hormones.

Vitamins and L-Amino Acids serve many essential functions related to plant health.  Like in humans, vitamins are essential for optimal health.  Deficiencies in specific vitamins can cause detrimental effects.

Plant benefits from ideal vitamin regulation include increased nutritional content, creation of enzyme co-factors necessary for plant function, and supplementing deficiencies during the plants life cycle; including during rooting, flowering and fruit set.

L-Amino Acids are also essential to successful, vigorous plants.  They increase root and leaf biomass, improve microbial activity, buffer heavy metals and salts, improve stress tolerance and chlorophyll synthesis; and are a source of organic nitrogen.

 

Diverse and Potent Biostimulants Grow The Best Plants

Dare to compare.  The diversity of species and potent concentration of EndoBoost Hydro is second-to-none.  This diversity and potency allows plants to be quickly established and optimized for maximum growth and health.

Healthy ecosystems contain massive amounts of diversity, and EndoBoost Hydro delivers an abundant complement of fungal and bacterial strains that give your plants the maximum benefits they need for success.

But why is that important?

Plants have been shown to use what is called Induced Systemic Resistance (ISR).  ISR is a response that is induced by beneficial bacteria and/or fungi that results in suppression of plant pathogens and pests, as well as promoting plant growth.

The selection of beneficial bacteria, fungi, and biostimulants in EndoBoost Hydro is no accident.  Research shows that combinations of biostimulants work in tandem to enhance plant growth and health.

The combination of ingredients in EndoBoost Hydro are highly selective to be the most dominant and effective to colonize plants, induce ISR, protect plants and induce growth.

For growers, this means you have the opportunity to have the best plants.

Effective and Versatile ‘Professional Grade’ Solution To Give You The Most Vigorous, Healthy, Productive Plants

Professionals and novices alike will appreciate the effectiveness and versatility of EndoBoost Hydro.  Research over decades has concluded that biostimulants have a prominent role to play in biointensive, regenerative, and productive agriculture and horticulture.

Regardless of your method, we have you covered.  Hydroponics, soil, coco coir, sphagnum peat, aeroponics, aquaponics.  EndoBoost Hydro will be effective in any soil or hydroponic growing setup.

All growers benefit from the versatility of EndoBoost Hydro.  Applied dry, in solution, as a root drench, injection; or any other method that gets direct contact with plant roots.  They are all effective.

 If you are a hydroponic grower, the benefits are even greater.  EndoBoost Hydro is dormant in dry form; unlike many liquid inoculants which use chemicals to suppress the microorganisms in solution.  With 1 tsp per 10 gallon concentration, EndoBoost Hydro is ready to be unleashed as soon as it is applied.  

One answer to give your grow the start it needs.  The benefits include:

  • Faster Plant Establishment (An Insurance Policy for your Plants).
  • Endomycorrhizae Colonize 92% of all Plant Families on Earth, and are the Backbone of a Healthy Rhizosphere.
  • The “Fungal Highway” Formed by Mycorrhizal Hyphae Moves Nutrients and Water from Abundant Areas to Deficient Areas, Resulting in Less Fertilizer Use Overall.
  • The Combination of Mycorrhizae, Beneficial Bacteria and Fungi Work Together to Protect Against Pests, Pathogens, and Stress, Lowering the Need For Pesticides.
  • The Biostimulants (Humic Acids, Sea Kelp Extract, Yucca Plant Extract) Feed and Assist this Diverse Living Amendment and Benefits All Plants in Any Kind of Grow.

Do your research, then compare the potency, diversity, and science to confirm that EndoBoost Hydro is is a true, all-in-one, professional grade amendment.  Guaranteed to Boost Your Grow The Natural Way.

What Are Plant Biostimulants and How Do They Benefit Plants?

Plant Biostimulants Defined

“A substance or microorganism that, when applied to seeds, plants, or the rhizosphere, stimulates natural processes to enhance or benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress, or crop quality and yield.”  This, according to the proposed 2018 U.S. farm bill establishes the first definition of biostimulants by any U.S. government entity.

“The inclusion of a definition for plant biostimulants in the Farm Bill represents a critical initial step in the legislative process that will ultimately support the development of new sustainable technologies for agriculture and U.S. farmers,” said David Beaudreau, Executive Director of the U.S. Biostimulant Coalition (USBC).

A slightly altered definition:  “A plant biostimulant is any substance or microorganism applied to plants with the aim to enhance nutrition efficiency, abiotic stress tolerance and/or crop quality traits, regardless of its nutrients content”<1>.  The key difference in this definition is the phrase, ‘regardless of its nutrients content,’ which in essence says that these materials can improve and enhance plant growth and function in ways that are not solely due to the nature of the material alone.  It is this statement that sets Plant Biostimulants apart from traditional plant fertilization.  Plant Biostimulants work as a complement to nutrients present and work in ways to make these nutrients more available to plants, among many other benefits.

With decades of development and scientific research citing the many benefits of biostimulants, the included definitions offer some legitimacy to a still emerging field.  With the potential to accelerate the use of these substances in sustainable agriculture/horticulture and other ways.

In this post, we will define the broad categories of Plant Biostimulants, and show how these materials work with plants and within a soil ecosystem to improve soil and plant health and productivity.

What Are The 3 Main Functions Of Plant Biostimulants?

  • Nutrient Use Efficiency
  • Stress Tolerance
  • Plant Quality Traits

Benefits of Using Plant Biostimulants 

  • Increased Nutrient and Water Uptake/Availability
  • Increased Root and Plant Growth
  • Tolerance to Abiotic Stress (Extreme Temperatures, Drought, Flood, High Winds, Nutrient Deficiency, Soil Compaction)
  • Improved Plant Performance, Quality, and Yields
  • Improved Soil Health, Function, and Performance
  • Increased Resistance to Pathogens

EndoBoost Pro Mycorrhizal Fungi

Categories of Biostimulants

  • Humic and Fulvic Acids
  • Seaweed Extracts and Botanicals
  • Beneficial Fungi
  • Beneficial Bacteria
  • Others (Protein Hydrolysates, Chitosan, Inorganic Compounds, etc.)

Humic and Fulvic Acids

Humic substances (HS) are natural constituents of the soil organic matter, resulting from the decomposition of plant, animal and microbial residues, but also from the metabolic activity of soil microbes using these substrates<1>.  Humic and Folic Acids hold similar functions in plant and soil benefits, with slightly different chemical makeups.  HS are the major component of humus, or the organic portion of soil.  

Common sources of commercially available HS are leonardite (mineral deposits), naturally humified organic matter (peat/volcanic soils), or chemically extracted from composts and agricultural by-products.

The benefits of HS for plants as well as soil are many.  HS are reported to play key roles in various soil and plant functions such as controlling nutrient availability, carbon and oxygen exchange between the soil and the atmosphere, and the transformation and transport of toxic chemicals.  In addition, humic substances in soils affect plant physiology and the composition and function of rhizosphere (root zone) microorganisms <2>.  Thereby increasing nutrient uptake, plant growth, and yield.  As well as indications that HS can have a positive effect against abiotic stress (drought, salinity, soil deficiency, etc.)

The results of studies have shown that HS are optimized when used in combination with plant growth promoting rhizobacteria (PGPR) and other biostimulants<2,3>.  Suggesting that using combinations of biostimulants containing HS may play a large role in developing more sustainable and eco-friendly agricultural practices.

Seaweed Extracts and Botanicals

The use of seaweeds and botanicals as biostimulants (biofertilizers) have been used in agriculture for millennia, as a soil amendment and to enhance crop productivity.  The effects of these various materials have been documented in research studies to have many benefits to both soil and plants.

Seaweeds and botanicals are renewable resources that have benefits as both biostimulants and biofertilizers, acting as a food source for plants as well as benefiting the soil biome in feeding PGPR. In soils, they act as chelaters, breaking down nutrients to feed plants, improve soil structure, as well as maximize water retention.  They also contain plant growth promoting hormones and other materials to aid in plant stress reduction (drought, salinity, and temperature extremes, etc.),<1,2>.

Common sources of seaweed extracts, such as Ascophyllum nodosum, contain over 70 trace minerals and vitamins, growth hormones, enzymes, and proteins.  Used in combination with PGPR, they have shown increases in root development, plant growth and yield, and have been shown to be effective in many agricultural and horticultural crops<2>.

Other botanicals, or extracts from plant substances, are being developed to assist in plant protection (biocontrol) products.  However, development of these extracts also show potential as biostimulants as well.  Similar to crop rotations, intercropping, cover crops and mulching, these materials show promise in allelopathy, or the beneficial interaction that occurs between plants.

Beneficial Fungi

The mutualistic benefits between plants and fungi have been evolving since the origin of plants on land, over 450 million years ago.  Mycorrhizal fungi form symbioses with over 90% of all plant species.  Many common agricultural and horticultural species associate with mycorrhizae, and the benefits of such have been widely documented. There is an increasing interest for the use of mycorrhizae to promote sustainable agriculture, considering the widely accepted benefits of the symbioses to nutrition efficiency (for both macronutrients, especially phosphorus, and micronutrients), water balance, biotic (living) and abiotic (non-living) stress protection of plants<1>.

The fungal networks formed by mycorrhizae have also been shown to create what are called hyphal networks.  These networks allow interplant signaling to occur, where plant defense mechanisms are triggered to defend against insect and fungal pests<5>.  Also, these hyphal networks allow for the movement of beneficial bacteria to where this signaling has occurred.

Other beneficial fungi, such as Trichoderma, have been identified to have their own unique benefits to soil and plants.  These fungi, unlike mycorrhizae, can live apart from plants; and have been reported to act as a biopesticide (biocontrol) agent and have plant growth promoting properties.  By colonizing plant roots, Trichoderma outcompetes pathogenic fungi, and induce plants to enable chemical defenses against certain pests.  They also promote plant growth through the release of growth enzymes and increase nutrient use efficiency<1,6>.

Beneficial Bacteria

Beneficial bacteria, specifically Plant Growth Promoting Rhizobacteria (PGPR) are multifunctional and influence all aspects of plant life.  Here are some of the ways this happens:

  • Help supply nutrients to crops;  
  • To stimulate plant growth, e.g., through the production of plant hormones;  
  • To control or inhibit the activity of plant  pathogens;  
  • Improved soil structure;  
  • Response to biotic and abiotic stress;  
  • Interactions with other organisms in the agroecosystems and bioaccumulation or microbial leaching of inorganics<1>.  

In this way, PGPR act as both biostimulants and biocontrol agents.  The soil, and specifically the rhizosphere, is the most biologically diverse ecosystem on the planet.  The inoculation of PGPR into these zones allow for plants to obtain the maximum benefit possible.  Much research has been conducted on the relationship between plants and PGPR<8>.

Similar to probiotics for humans, PGPR are recruited by plants to assist in improved nutrition and immunity.  Using the Mycorrhizal network, PGPR can be signaled, and move to assist the plant in defending against pathogens.  This occurs through the release of specific compounds that trigger a response from either the plant or the bacterium.  Many beneficial soil-borne microorganisms have been found to boost the defensive capacity in above-ground parts of the plant.  This induced systemic resistance (ISR) is a state in which the immune system of the plant is primed for accelerated activation of defense.  Where plants have been shown to signal for specific bacteria based on specific conditions<7>.

The potential for beneficial bacteria use in biointensive growing has been widely studied, and a diverse combination of bacteria affords the best opportunity to allow for plants to gain the maximum benefit in health and vigor.

Others (Protein Hydrolysates, Chitosan, Inorganic Compounds, etc.)

Other forms of biostimulants also have benefits to soil and plant health.  Protein hydrolysates are acquired from plant or animal byproducts.  They include amino acids and have been shown to increase Nitrogen uptake, regulate hormones and enzymes, and chelate nutrients.  Protein hydrolysates are known to increase microbial biomass and activity, soil respiration and, overall, soil fertility. Chelating and complexing activities of specific amino acids and peptides are deemed to contribute to nutrients availability and acquisition by roots<1>.

Chitosan and inorganic compounds also contribute in similar ways to optimize soil and plant health.  Many effects of beneficial elements are reported by the scientific literature, which promote plant growth, the quality of plant products and tolerance to abiotic stress<1>.

Chitosan and inorganic compounds also contribute in similar ways to optimize soil and plant health.  Many effects of beneficial elements are reported by the scientific literature, which promote plant growth, the quality of plant products and tolerance to abiotic stress<1>.

Reported Examples of the Main Effects and Physiological Actions Played by Plant Biostimulants

Plant Biostimulants Benefit Plants

The research is extensive, and ongoing.  The results are documented.  Numerous plants species have been cited to positively benefit from biostimulant use.  A growing awareness is occurring that there is a better way from the traditional methods used in farming and horticulture.  Feed the living soil, feed the plant.  Biostimulants improve soil health, optimize nutrient use, and increase plant growth, vigor,  yield and production.

The work that biostimulants perform allows for less fertilizer use and less need for pesticides, and also shows potential to be useful in site restoration/remediation<2>.  The research into the benefits of biostimulants, and the methods to maximize those benefits continues.

A more biointensive and sustainable agricultural (horticultural) environment is possible.  Build a living soil that is more resilient, regenerative, and let nature do the work.
