The Pros and Cons to DIY Compost Tea

compost tea

Lately, human probiotics seem to be all the rage. It’s seen as a hip, new science found in the form of yogurt and pills that restore your body’s health. Human probiotics is the idea of introducing beneficial or benign microorganisms to our gut to naturally boost gut health.

Just as with human probiotics, plants need probiotics too! Soil microbes help the plant carry out daily functions and can lead to optimized plant resilience, increased yields and a stronger more web-like root system.

Perhaps one of the most common methods of incorporating plant probiotics into a plant health program is by applying compost tea.


Plant’s “Tea of Choice”: Compost Tea

Named for its murky brown tea-colored resemblance, this brewed, water extract of compost works to increase the amount of nutrients and soil microbes available to the plant as well as extending numerous other benefits that come from traditional compost. There are both pros and cons for incorporating compost teas; see below for some of our highlights.


Advantages of Compost Teas

Inexpensive – By applying compost tea to your plants, you reduce the need for fertilizers and pesticides, ultimately driving down the cost to keep plants healthy.

Aids in Producing a Healthier Plant – When applied, compost tea suppresses foliar diseases and speeds up the breakdown of toxins. Compost tea increases the amount of nutrients available to the plant through microorganism processes, resulting in an overall healthier plant.

Organic – Because it’s made up of natural components, crops nurtured with compost tea are organic, giving you a competitive edge in the plant health/organic world.

Easy to Make – With the right tools and components, compost tea can be made by just about anyone who has good organizational skills.


Disadvantages of Compost Teas

Inconsistent Products – There are many variables in producing compost tea including: compost, water, food materials, time of processing, good record keeping and sourcing materials. In order to ensure consistent results, brewers need to be exact in their recipe-building and production process. Even when brewers are organized in their production and recipe, each batch differs slightly from the last.

Inconsistent Results – Though they might be the same kind of plant, not every plant is exactly the same. As a result, the benefits from applying compost tea can differ slightly per plant.

Lack of Scientific Proof – Compost tea recipes are mostly made up of “he said, she said” gardener testimonials rather than actual scientific proof; therefore, following these recipes can generate unreliable results.

Time Consuming – Because of the “brewing” process, producing compost tea can often be time consuming, and once produced, compost teas must be applied shortly after for best results.


Holganix Can Help!

Brewing your own compost tea is tricky, but Holganix can help! Holganix’s flagship product Bio 800+ is a plant probiotic derived from a compost tea base that contains over 800 species of beneficial soil microbes. Because of our manufacturing process, we ensure product consistency and DNA fingerprint each batch to understand which species of soil microbes are present.

Humus – The Essential Ingredient

Humus is what is left after soil microorganisms have decomposed organic matter. It holds nutrients and moisture and provides a great structure for planting in. Humus is essential for food production and is being gradually depleted. Learn more in Graeme Sait’s TED Talk.


Healthy Soil, Healthy World 

If you pick up a handful of soil, you will be holding more microorganisms in your hand than the entire number of people who have ever lived on earth. Think about that for a moment. Can you imagine the quantity of living things in your grasp? Soil is FULL of life. In this TED Talk you’ll have the opportunity to explore the soil from a microorganisms’ point of view.


Putting Carbon Back Where It Belongs

Good news! Plants can quite literally change the face of the earth. By growing more plants, we can capture more carbon dioxide, water, production, biodiversity and profit? In fact, a 1% change in soil organic matter across just one quarter of the world’s land area could sequester 300 billion tons of physical C02. Check out Tony Lovell’s TED Talk here.


Stop Treating Our Soil Like Dirt!

Healthy soil is not dirt! Healthy soils are critical for keeping water clean producing food and buffering the effects of extreme weather. Soil plays a fundamental role in our lives in three key ways… Watch Karen Wynne’s TED Talk here.


Soil – From Dirt To Lifetime 

Did you know there are more living organisms beneath the soil then there are above it? Soil scientists can’t even come to an agreement about how many microbes are actually in the soil. Check out Fred Kirshenmann’s TED Talk here.

What You Don't Know About Sustainable Agriculture

Sustainable agriculture plays a big role in today's farming industry and it's shaping the way the world grows organic, low input or holistic crops.

Check out our slideshare below for seven key facts to know about sustainable agriculture. If you're reading this blog via email and having difficulty viewing the slideshare, click here: What You Don't Know About Sustainable Agriculture 

Soil health is crucial to sustainable agriculture
Having healthy soil means you have a better growing habitat for crops. When our soil ecosystem is in balance, crops are better able to handle stresses and need less inputs like fertilizers. Nurturing soil health means big improvements in sustainability.
Leonardo da Vinci once stated, "we know more about the movement of celestial bodies than the soil underfoot." Today's technology and research is doing a lot to close that gap. Update your knowledge on soil health by downloading our Digging into Soil Science Ebook.

Top 5 Techniques to Improve Sustainability at The Farm


Sustainable agriculture is becoming increasingly important. However, farmers looking to improve sustainability at the farm are faced with the overwhelming challenge of producing high-yield, high-quality crops without undermining the natural systems and resources that crop productivity and environmental sustainability depend on. That challenge is becoming even more crucial when faced with today’s growing world population, which is forecasted to reach 9.7 billion by 2050.

We’ve compiled a collaboration of some of the most popular sustainable agriculture techniques employed by farmers today. These techniques help farmers increase yields and crop resilience, gain control over weeds, pests, disease, erosion, and aid in producing high-quality soil.


#1 Using big data to create field-specific applications

Instead of treating a field uniformly, precision agriculture uses big data to prescribe site-specific treatments utilizing technology like GPS and GIS. This micromanagement of a farm allows farmers to (1) provide the ideal recipe for growing the best crops possible on a specific location based on the needs of the soil and crop and (2) minimize their environmental footprint by using fertilizers and pesticides only when needed.


#2 Adding microbial products to boost yields and crop resilience and reduces the need for fertilizers and pesticides 

Instead of adding nutrients, microbial products add living, beneficial microorganisms that naturally increase crop and soil health the way Mother Nature intended. While seen as a new technology, data from microbial products demonstrate that soil microbes have the power to affect big change in the agriculture industry.

For example, Holganix Agriculture (aBio 800+ product) is a 100% organic microbial product, infused with over 800 species of diverse microbes to optimize your soils. Studies have shown that Holganix Agriculture increases yields and crop resilience when faced with stress, and reduces the need for fertilizers and pesticides.

Want to learn more about results seen with Holganix Agriculture? Check out our case study “Boosting Yield and Degrees Brix at Alfalfa Farm Winery”:


#3 No-till/soil enrichment enhances soil health and decreases erosion and runoff

No-till farming helps prepare the land for crops without mechanically disturbing the soil. There are countless benefits that come with adopting no-till farming including a significant decrease in soil erosion, an increase in water infiltration and retention by the soil (resulting in less runoff of water that is often contaminated with fertilizers and pesticides) AND because the soil is not being frequently agitated, no-till farming promotes biodiversity in and around the soil.


#4 Cover crops alleviate compaction and protect from erosion

Planting cover crops such as clover, oats, or radishes help alleviate compaction so oxygen and water can sufficiently flow in the soil. It also adds organic matter to the soil when tilled under for the next farming season and helps hold soil in place, reducing crusting and protecting against erosion from wind and rain.

For additional information regarding cover crop benefits, watch the video below by The Soil Health Institute. If viewing this blog via email, click here to view the video.




# 5 Crop rotation naturally curbs pest problems

Crop rotation allows farmers to curb pest problems naturally. Many pests have preferences for specific crops; therefore, the continuous growth of the same crop guarantees pests a steady food supply. By growing different crops in succession in the same field, you help break that food supply and control pests.

What are plant growth promoting bacteria?


Plants aren’t as vulnerable as they appear. Soil microbes form symbiotic (mutually beneficial) relationships with the plant, offering to boost plant defenses and plant growth in return for food sources.

Plant Growth-Promoting Bacteria (PGPB) is a special class of bacteria that occupy the rhizosphere (root zone) of the plant and have the ability to promote plant growth and plant defenses.


PGPB directly affects plant growth

PGPB directly affects plant growth by facilitating the availability of nutrients such as nitrogen, phosphorus and iron. These nutrients are critical to plant biochemistry, and without them plant growth is limited. While nitrogen, phosphorus and iron may be abundant in the soil, they are often found in a form the plant can’t utilize. PGPB convert those nutrients to the form the plant can use.

PGPB can also produce plant hormones like auxins, gibberellins and cytokinins that stimulate plant root and shoot growth in exchange for food sources from the plant.


PGPB protects the plant

PGPB has the ability to protect the plant from pathogens through microbial antagonism. PGPB out-compete pathogens for nutrients and produce antibiotics and anti-fungal metabolites.

PGPB also have the ability to help the plant defend itself from pathogens through Induced Systemic Resistance (ISR). ISR triggers a signal in the plant that activates the plant’s defense system such as reinforcing plant cell walls, producing anti-microbial phytoalexins and synthesizing pathogen-related proteins.


PGPB found in Holganix Bio 800+

Holganix Bio 800+ is our product line of plant probiotics containing over 800 species of beneficial microorganisms, microbe food and nutrient enhancers to promote optimal plant health with less fertilizers, pesticides and water needed.

One of the important ingredients in Holganix Bio 800+ is PGPB. In order to ensure that each batch is teeming with PGPB, Holganix uses DNA fingerprinting as a critical function to its manufacturing process.

At Holganix, we are self-appointed soil geeks. Learning about new trends, research and theories that are happening in the field make us tick. We bet it gets you excited too! Here are our top 5 favorite articles on soil microbes (to be fair, some are videos).


Healthy Soil Microbes, Healthy People

The Atlantic Magazine reports that the microbial community in the ground is as important as the one in human guts. According to the Atlantic Magazine, “The greatest leverage point for a sustainable and healthy future for the several billion people on the planet is arguably immediately underfoot: the living soil, where we grow our food.”

Read Healthy Soil Microbes, Healthy People by Atlantic Magazine:


Microbes Help Grow Better Crops

Scientific American explores research from Virginia to Colombia that has been conducted on microbes to boost plant health and crop yield. “Microbes act as sentinels of food safety and furnish an environmentally sound alternative to massive inputs of fertilizers and pesticides,” says Scientific American.

What is the Soil Food Web?

Within the soil exists a complex balance between the soil microorganisms and larger organisms such as earthworms, insects, small vertebrates and plants. All of these organisms live all or part of their lives in the soil.


Soil Food Web Diagram from the USDA 

To steal a line from Walt Disney’s The Lion King, it’s the circle of life! The larger organisms consume smaller organisms; those smaller organisms consume even smaller organisms and so on. When complete, the soil food web nurtures healthy plants, healthy habitats for those plants and an overall healthier environment with less pollutants. When the soil food web is out of balance, plant health is compromised.




What are soil microorganisms and why are they important to plant health?

Soil is abundant with living microorganisms including bacteria, fungi, actinomycetes, protozoa, algae and nematodes. Of the microorganisms present in most soils, roughly 95% of the total population is bacteria.

These microorganisms carry out important functions in the soil to nurture plant health including but not limited to: converting and releasing nutrients (plant food) to the plant; promoting plant tolerance from stress including weather, disease and traffic; fighting pathogens in the soil; and stimulating plant growth.


Reducing inputs when using microbial products

New products that contain microorganisms have been gathering market support. Turf professionals, horticulturists and farmers report needing less fertilizers and pesticides when using microbial products in combination with their traditional fertility program.

One example is Broken Sound Country Club in Boca Raton, Florida. Shannon Easter, Director of Golf Maintenance, has reduced fungicide use by 30% and fertilizer by 20% when using Holganix Bio 800+ in combination with his fertility program.

Holganix Bio 800+ is a microbial or plant probiotic containing more than 800 species of active microorganisms to nourish plant health.

Jimmy Cox of Picture Perfect Lawn Maintenance has reduced fertilizer use by nearly 50% with Bio 800+. Jimmy is using 2.2 pounds of nitrogen, down from his usual 4 pounds annually.

What is Holganix Bio 800+?


At Holganix, one of our core values is Evolution & Revolution. What does that mean? (1) we want to create a revolution in the green industry and (2) we believe in continually evolving our business and products to make them better and better.

With a focus on biology as the solution to plant health, Holganix is continually pioneering (dare we say, revolutionizing…) new methods of incorporating biology to build resilient plants and healthier soils. After all, fostering healthy plants begins by fostering healthy soils that are teeming with beneficial soil microorganisms.

As our industry evolves, we are excited that plant probiotics are becoming steadily accepted by the industry. However, as competitors emerge, we felt the need to evolve our brand and rename our flagship product line (the liquid, refrigerated products like Holganix Lawn, Golf, Tree and Shrub and Bloom) to differentiate it from the competition.

That is one of the reasons why Holganix is channeling its core value of Evolution & Revolution to re-named its flagship product line as Bio 800+.


Why Bio 800+?

Bio stands for life; 800 stands for the number of microbe species present in the product line; and + stands for more than or beneficial. In other words, Holganix Bio 800+ contains over 800 species of beneficial, living microorganisms (click to access the ingredient list). That’s a lot of bugs in our jug!

what does it mean-2.jpg

In fact, if you compare Holganix Bio 800+ to the competition, you’ll notice that all other products contain 2 or 3 or maybe 6 species of microorganisms that target specific plant problems.

When it comes to microbial products, the microbe count is important, yet diversity can be even more crucial. By having a product filled with a diversity of life, the soil and plant is prepared for whatever hurdle it needs to face.

Think of it as your equivalent to a multi-vitamin. Instead of a magic bullet, Holganix Bio 800+ products parachute in an army of specialists, each of which is capable of filling in gaps to balance the biological requirements of the soil.

Consider the environment you are asked to grow plants in. Are the soils the same from property-to-property? Do the climate conditions change day-to-day or hour-by-hour? Are the pathogens and stresses that are attacking your plants changing? Don’t you want to give your plants every possible advantage to adopt and respond to all of these changing challenges?  

Whereas a single microbial strain would be able to assist with one single, targeted problem, a microbial product with a huge diversity of species is better equipped to handle problems in a changing environment.

Just as a car can’t be fixed with a single screwdriver, Holganix Bio 800+ is an entire toolbox of microbes adept to handle numerous problems.

In a nutshell, Holganix Bio 800+ is a complete ecosystem in a jug that harnesses the power of over 800 species of beneficial microorganisms to:

1. Increase the plant's tolerance of stress from weather, disease and insect

2. Stimulate healthy foliage and root growth

3. Reduce inputs including fertilizers, pesticides and water

4. Many other benefits!



How can Holganix stuff so much life into a jug of Holganix Bio 800+?

When looking at microbial products, like Holganix’s Bio 800+, it’s not uncommon to be stumped by the ingredients. After all, the product is living and changing; how can you really be certain that you are applying a viable product?

Because Holganix is committed to producing quality product, Bio 800+ is:

1. Field and university tested

Holganix spends six-figures annually on university testing to learn more about our product and to validate claims. To read the cliff notes from our University Studies click here. Holganix also has recorded 70+ case studies across America. To access our favorite case studies click here.

2. DNA fingerprinted for product consistency

Each batch of product is DNA fingerprinted to ensure that each batch produced is living (literally) up to Holganix’s quality standards.

3. Refrigerated to keep the life dormant and fresh for use

At the end of the day, you can keep a couple or a few microorganisms dormant without refrigeration. But, to keep the diversity and quantity of microorganisms present in Bio 800+ fresh and ready for use, refrigeration is key.

4. 100% organic

To keep our product safe for people, pets and the environment, Holganix Bio 800+ is 100% organic.

What’s really in a jug of Holganix Bio 800+?

what does it mean-334501-edited.jpg

When looking at microbial products, like Holganix’s Bio 800+ (the liquid, refrigerated products), it’s not uncommon to be stumped by the ingredients. After all, the product is living and changing; how can you really be certain that you are applying a viable product?

That’s one of the reasons why Holganix performs DNA fingerprinting to ensure that batches of product contain the appropriate species of microorganisms, each time it’s produced.

That begs the question, what really is in a jug of Bio 800+? How much life can Holganix possibly stuff into a jug?

It turns out that Holganix can stuff quite a lot of life into a single jug of product… more than 800 species of microorganisms to be exact.


More than 800 species of microorganisms are in Holganix Bio 800+

Bio 800+ products (Lawn, Golf, Tree and Shrub, Bloom and the Agriculture Blends) provide the complete ecosystem of microorganisms needed for soil and plant health. Containing more than 800 species of beneficial microorganisms, microbe food and nutrient enhancers, Bio 800+ is changing the soil at a fundamental level to build strong roots and resilient plants.


Why do microorganisms matter?

Microorganisms found in the soil include archaea, bacteria, protozoa fungi and beneficial amoeba, with bacteria leading in species, count and density. In fact, in one gram of soil, there are up to 1 billion bacteria, representing as many as 700,000 species.

These microorganisms create healthy soils that feed the plant with nutrients, defend the plant from pathogens and increase the plant’s ability to perform under stress.


How does the process start?

Holganix Bio 800+ products begins as a patented green compost extract from one of 11 climate zones across the United States, containing 296 genera, more than 800 species of microorganisms that foster a diverse soil ecosystem.

When it comes to microbial products, the microbe count is important, but diversity is even more crucial. By having a product filled with a diversity of life, you prepare the soil and plant for whatever hurdle it needs to face.

Think of it as your equivalent to a multi-vitamin. Instead of a magic bullet, Holganix Bio 800+ products parachute in an army of specialists, each of which is capable of filling in gaps to balance the biological requirements of the soil. 

how holganix works mini [1].jpg


Looking at bacteria in Holganix Bio 800+

Many of the bacteria species found in Holganix Bio 800+ products are plant growth-promoting bacteria (PGPB). These PGPB provide plant hormones (auxin, gibberellin and cytokinin) to stimulate growth, make nutrients available to the plant, protect the plant from disease and produce biosurfactants (wetting agents).


Looking at fungi in Holganix Bio 800+

Holganix Bio 800+ products also include several species of fungi, including Trichoderma, Penicillium and Endo and Ecto Mycorrhizae. Trichoderma Fungi colonize roots, attack fungi and induces the plant’s natural defense system. Penicillium Fungi break down organic matter, releasing organic acids and nutrients, while Endo and Ecto Mycorrhizae assist with water, mineral and nutrient uptake.


Other sources of life in Holganix Bio 800+

Additional types of microorganisms include protozoa and beneficial nematodes.


Microbe food is also a key ingredient

Just as microorganisms play an important role in plant health, so do microbe food, albeit in a more indirect way. Microbe food provides the resources needed to nourish the soil microorganisms, creating an ideal habitat for both the microorganisms and the plant.

Examples of some of the microbe food contained in Holganix Bio 800+ include Gluten, Saccharomyces Cerevisiae (Brewer’s Yeast), Auxins, Kelp, Yucca and microorganisms.


Looking at nutrient enhancers

Nutrient enhancers stimulate better uptake of nutrients by the plant, allowing you to optimize your fertilizer use, reduce fertilizer use and contribute to less nutrient run off to the environment.

Nutrient enhancers in Holganix Bio 800+ include Humic and Fulvic Acids, Amino Acids, Kelp and PGPB. Many of these PGPB act as bio fertilizers because they can fix nitrogen, solubilize phosphorus and potassium and create chelates (solubilizing agents) of micronutrients.


“Better ingredients? Better Turf!” – Dr. Cale Bigelow

In a previous Holganix Webinar, Dr. Cale Bigelow of Purdue University stated, “Better Ingredients? Better Turf!” While the quote was not in reference to Holganix products, we can’t help but steal the quote to sum up our article.

When looking at microbial-type products (Plant and Soil Probiotics), the better the ingredients in the product, the better the result. With the power of more than 800 species of microorganisms, microbe food and nutrient enhancers, we are willing to bet that Bio 800+ products contain the most diverse life in a single product on the market.

Time to conduct a soil test!

Stock Test Tube + Soil and plant-173483-edited.jpeg

When was the last time you took soil tests at your property? Are your plants looking a little worn out? Are your turf and plants not taking to fertilizer applications?

Soil tests provide the key soil health metrics you need to better prescribe a fertility program for your property.

On a basic level, soil tests indicate nutrient deficiencies and pH levels. However, more advanced soil tests are available that also indicate Cation Exchange Capacity (CEC), soluble salts and other important soil health metrics.

What is each of the soil health metrics you can expect from a soil test, what do they mean and what practices can you put in place to improve results?


Measuring key elements to plant growth

According to the University of Minnesota Extension, “There are at least 17 essential elements required for plant growth: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, chlorine and nickel.”

While elements like hydrogen, carbon and oxygen are taken from air and water, the remaining elements are derived from the soil. When the soil is lacking in a key element, adding a fertilizer is key.

The three most important nutrients for plant growth include: nitrogen, phosphorus and potassium.

1. Nitrogen is responsible for stimulating strong plant growth and promoting green coloring of foliage (it helps with chlorophyll production). Nitrogen is often present in the soil; however, it may be locked in a form that isn’t utilized by the plant. Adding a fertilizer containing nitrogen will directly supply the nutrient to the plant. You could also add a probiotic containing nitrogen-fixing bacteria that will unlock nitrogen already present in the soil, making them available to the plant.

2. Phosphorus is responsible for assisting with the growth of roots and flowers. It also helps plants withstand environmental stress and harsh winters. Just like with nitrogen, phosphorus is often contained in the soil but may be locked in a form the plant can’t use. Adding a fertilizer containing phosphorus or adding a probiotic containing phosphorus-solubilizing bacteria can increase the supply of available phosphorus.

3. Potassium strengthens plants, contributes to early growth and helps retain water. It also affects the plant’s disease and insect suppression. Adding a fertilizer containing potassium will offset any imbalances in the soil.

>>For information on the six essential nutrients for plant health, read our blog here.


Looking at soil pH

Soil pH is a measure of soil acidity. A pH of 7 is neutral; anything below a 7 is acidic and anything above is alkaline.

According to the University of Minnesota Extension, “A soil pH is an important chemical property because it affects the availability of nutrients to plants and the activity of microorganisms in the soil.”

On average, most plants prefer a soil pH between 6.0 and 7.0 and most turf grasses prefer a pH of 5.5 and 6.5. However, pH can differ depending on the plant and turf grass you are growing.

Adding a lime is one common practice to raise the soil pH. Tools that lower pH include but are not limited to: sulfur, iron sulfate, aluminum sulfate, acid sphagnum peat and ammonium sulfate/urea.


Cation Exchange Capacity

Think of the soil as the pantry for plants, storing the necessary nutrients to feed the plant and ultimately boost plant health. The Cation Exchange Capacity (CEC) is the soil’s ability to maintain and release nutrients to the plant.

So, the higher the CEC, the larger the pantry and the more “food” the soil has the ability to store and feed to the plant.

To increase CEC levels, adding a product with high microbial populations will stimulate the digestion of organic matter, increasing humus levels, which thereby increases CEC levels.

>>Dig deeper into Cation Exchange Capacity and how Holganix boosts CEC levels


Soluble salts

Soluble salts are the ions that are dissolved in soil water.

Why are soluble salts important? “High soluble salts can reduce water uptake by plants, restrict root growth, cause burning of the foliage, inhibit flowering, and limit fruit and vegetable yields.” 

Some soils naturally have high soluble salts, however human practices like over fertilizing, pet urine, or using snow salts on sidewalks/streets can all increase soluble salt levels.

To correct soluble salt problems, look at incorporating gypsum and leaching the soil with good quality water.


How and where do you conduct soil tests?

Results from soil tests often take a couple weeks and possibly a couple months depending on the test. Most university extensions offer soil testing.

Utilize a sampling tube and take several samples at each location of your property. Look at taking 3-inch to 6-inch deep soil samples. Remember to label each tube with the location from your property from which it was taken.
