plants including, increased nutrient uptake, phosphate solubilization, and the product of plant growth hormones, phytohormones.

Multiple types of microorganisms are used as biofertilizers such as Trichoderma fungi and bacteria. Biofertilizers are beneficial soil microorganisms.


Benefits of Using Biofertilizers

Bio fertilizers will help plants grow larger, healthier plants. In turn, these healthier plants will produce more and larger fruits and vegetables.

The greatest benefit of bio-fertilizers is the effect of beneficial microorganisms on the root system of the plant. The beneficial microorganisms form a synergistic relationship with the plants’ roots. This help the plant grow larger, healthier, and better developed roots. This allow the plant greater access to nutrients and water. Both key elements in plants growth.

PGPB – Plant Growth Promoting Bacteria


Plant Growth Promoting Bacteria, or PGPB, are a major factor in determining plant health, plant productivity and overall soil fertility.

What are PGPB?

Plant growth promoting bacteria, present in the rhizosphere, are beneficial soil bacteria that enhance plant growth and reduce the abiotic stresses through a variety of mechanisms.

Since these beneficial bacteria are found in the rhizosphere, you will sometimes see the term PGPR, plant growth promoting rhizobacteria, used.

Several plant microbe interactions are generally classified as PGPB including:PGPB Plant Growth Promoting Bacteria

  • Phosphate solubilization
  • Biological nitrogen fixation
  • The production of phytohormones
  • ACC deaminase activity
  • The production of siderophores

Benefits of PGPB’s

There are several specific benefits to  the plant of plant growth promoting bacteria, including; increased agronomic activity, reduced overall production costs, and reduced environmental pollution.

Increased agronomic activity is the goal of every farmer, both commercial and home gardener. The use of PGBR increases root size and root strength in plants. In turn, these healthier roots help produce stronger, more productive plants.

The reduction in environmental pollution is achieved because less traditional fertilizers (N,P,K) are generally needed when sufficient amounts of plant growth promoting bacteria are added. This means that the fertilizers are used more efficiently. This efficient usage reduces costs and fertilizer runoff issues. Less use of N,P,K, means less fertilizers wash away. Since fertilizer runoff is a major environmental issue, use of PGPB reduces this problem.

For beneficial bacteria to be effective, several factors must be considered:

  • Overall soil condition, including soil pH, water, minerals, soil porosity
  • Extent of bacterial colonization of the root zone
  • Amount and types of plant exudates

The Future of Beneficial Microbes

Plant growth promoting bacteria have only recently become of interest to scientists and farmers. Over the next decade, I fully expect much more research will be done in this promising area.It is worth noting that by 2019, the agricultural microbials market is expected to reach 2.45 Billion USD.

Commercial Products

Custom Biological manufactures both Custom B5 and Custom N2. Both if these products are PGPB’s. Additionally, Biota Max™ contains both plant growth promoting bacteria and plant growth promoting fungi.

Trichoderma Biofertilizer

Trichoderma Biofertilizer

Commercial Trichoderma biofertilizers are becoming more common and more misunderstood. In this post, I’ll discuss the use of beneficial Trichoderma fungi as a biofertilizer.


Trichoderma are a microscopic fungi that are naturally present in most soils. To insure high populations of Trichoderma or to replenish populations lost to over farming, Trichodema can be added to soils by the use of Trichoderma biofertilizers. These fertilizers have a number of important benefits to the plant:

  • Reduces the use of traditional fertilizers (Nitrogen, Phosphorus, Potassium). Reduces the pollution from overuse of NPK.
  • Improves plant growth, crop yield, and nutritional quality.
  • Form a symbiotic relationship with plant roots increasing tolerance to plant stress such as drought.
  • Production and release of beneficial plant growth hormones.
  • Takes advantage of microbe plant interactions.

Trichoderma Biofertilizer

Trichoderma biofertilizers have been used successfully with a number of crops including tomatoes, corn, rice, sorghum, soybeans and peppers.

Custom Biologicals manufactures and distributes three products that contain Trichoderma Trichoderma Biofertilizerfungi; Custom GP, Biota Max™ and Custom GP Fizzytabs.

All three products are Trichoderma biofertilizers and contain 4 species of beneficial Trichoderma fungi. They include:

  1. Trichoderma harzianium
  2. Trichoderma viride
  3. Trichoderma koningii
  4. Trichoderma polysporum

All three products are designed as soil conditioners. That is they are to help improve soil conditions by increasing the populations of beneficial soil microorganisms.

Custom GP is a liquid concentrate and contains 4 species of beneficial fungi. Custom GP is also available as a fizzytab.

Biota Max™ contains both beneficial Trichoderma and beneficial soil bacteria. As a combination product, Biota Max™ is unique to the biofertilizer industry. Each tablet treats 1/4 acre or 1/10 hectare. Biota Max™ is equally useful in the home garden and the commercial farm. Great as a seed treatment too!

Trichoderma for Plants

Beneficial Trichoderma fungi convey many benefits to plants. In fact, microbe plant interactions are often beneficial to the plant and in turn, beneficial to farmers and gardeners. This post will talk about the plant growth promotion benefits of these beneficial fungi.

Basics of Beneficial Fungi

First, lets start at the beginning. Trichoderma are microscopic, free living fungi typically Trichodermafound in the root zone (rhizosphere) of many plants. They are common inhabitants of both the root and soil ecosystems. They  are generally thought of as opportunistic, avirulent plant symbionts.

In fact, some species are able to colonize and grow on roots as the roots develop. For this reason, many applications  are either as seed treatments or applied as early in the growing cycle as possible.

Since many fungal species have a number of benefits for plants, there are a number of words use to describe these benefits such as; biofertilizer, soil probiotic, soil inoculant, biological soil enhancement and plant growth promoting fungi.

Plant Growth Promotion

For many years, it has been known that many Trichoderma species help with plant growth promotion. They, along with multiple species of Mycorhiza, are considered plant growth promoting fungi (PGPF). Enhanced root development has been seen in a number of crops including, soy beans, corn, tomatoes, peppers and rice to name a few.

Root development is key to a plants early survival as well as its nutrient uptake as the plant begins to mature. All gardeners and farmers know, that a plant with a good root system will become a productive plant.

Along with enhanced root development, beneficial soil fungi convey some additional specific benefits to plants:

  • Phosphate solubility – making phosphorus more readily available to the plant.
  • Enhanced root biomass production and enhanced root hair production.
  • Production of phytohormones – both auxins and cytokinins. These compounds are plant growth promoters.
  • Higher tolerance of the plant to stress.

All of these benefits ensure a healthier, more efficient root system, a healthier plant and a more productive crop.

Commercial Products of Custom Biologicals

There are a number of commercial products, including Custom GP by Custom Biologicals and Biota Max™.

Custom GP is unique among the commercial formulations:

Probiotics and Rice

Probiotics and Rice

Field Trials


Probiotics and Rice field trial information. The soil probiotic used in the field trial is Biota Max™. Soil probiotics are sometimes called biofertilizers or biological soil amendments.

Biota Max

Biota Max™ is a soil probiotic containing beneficial soil microbes, both beneficial soil bacteria and beneficial soil fungi. Biota Max™ is a unique, effervescent tablet  that dissolves easily and quickly in water. Once dissolved, each Biota Max tablet will treat 1/4 acre (or 1/10 hectare) with billions of beneficial microorganisms.

Soil Probiotics and Plant Roots

These beneficial soil microorganisms help the plant grow larger, healthier root systems.These larger, healthier roots help grow bigger and more productive rice plants. Healthier roots help plants take in and process more nutrients and take up more water. A more efficient uptake of fertilizers and water means less waste and less runoff. Typically, using Biota Max™ also reduces  the amount of Nitrogen needed.

I’ve attached the soil probiotics and rice field trials below. A couple of interesting things to note.

  • The roots in the untreated versus treated with Biota Max™ – great pictures of bigger, healthier roots.
  • The yield increases in the treated versus untreated. In fact, the rice yield increased 11.3%, 16.6%, or 26.8% depending on the treatment method.
  • The overall health and look of the plants.
