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.

Trichoderma species. Trichoderma viride.

Trichoderma Species used as Biofertilizers

There are several species of Trichoderma fungi that are used as biofertilizers. In this post, we’ll talk about the most commonly used Trichoderma.  We’ll also talk about the benefits of using Trichoderma for farming, agriculture and home gardening.

Trichoderma Fungi

First, some background on Trichoderma fungi, such as Trichoderma viride. Trichoderma species are the most prevalent

type of fungi in soils and they are present worldwide in almost all soil types. They are microscopic and are generally considered avirulent plant symbionts. In other words, they form a symbiotic, or mutually beneficial, relationship with plants.

Its this symbiotic relationship that biofertilizers try to exploit. The idea is simple, by adding more Trichoderma the plant receives more benefit.

Benefits of Trichoderma

I’ve discussed the benefits to the plant of Trichoderma in another post, so I’ll just summarize the highlights here.

  • Trichoderma generally increase both root and shoot growth.
  • Improves the nutrient status of the plant
  • Production of growth promoting hormones
  • Phosphate solubilization
  • Increased uptake of minerals such as Cu (copper), Fe(Iron), Zn (Zinc), and Na (Sodium).

Trichoderma Species Used as Biofertilizers

Most of the Trichoderma species listed here provide the benefits from above. I’ll talk a bit about the additional benefits of some of the fungi. It’s important to note that Trichoderma applications can be made as seed treatment, as a foliar treatment, or as a drench treatment.

Trichoderma harzianum increases plant tolerance to environmental factors like drought and high soil salinity. T. harzianum increases mineral absorption.

Trichoderma viride, when used as a seed treatment, increases the germination rate in a number of crops.

Trichoderma reesi has the ability to secrete large amounts of cellulolytic enzymes and has a number of uses in biotechnology. In fact, it is used to create stone washed jeans because of this ability.

Trichoderma koningii is known to increase the growth of seedlings and secretes seed germination factors.

Trichoderma polysporum is normally found in cooler climates and conveys all of the benefits associated with the other Trichoderma fungi.

Custom Biologicals

Custom Biologicals manufactures a number of Trichoderma based products, including Custom GP. Custom GP is a concentrated liquid biofertilizer containing 4 species of beneficial Trichoderma fungi. Contact Custom for more information about using biofertilizers in agriculture, farming and gardening.

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.

Nitrogen Fixing Product Case Study

Green Soybean Case Study With Custom N2

Role of Nitrogen Fixing Bacteria

Custom N2 is a nitrogen fixing product that increases the nitrogen content of the soil. The role of notrogen fixing bacteriaN2 contains a nitrogen fixing bacteria Paenibacillus polymyxa. This beneficial soil bacteria takes atmospheric nitrogen (N2) and converts it to ammonium. The ammonium is then usable to the plant.

Nitrogen fixation is a vital process for the plant as nitrogen is a key element in plant growth.

Custom N2 improves root size and root health. This healthier root allows the plant to take up additional nutrients thereby improving overall yield and quality of the crop.

Green Soybean Case Study

Green soybean, called edamame in the United States, needs a large quantity of nitrogen to grow and produce crop. In this case study, we added Custom N2 and had a much larger yield of edamame.

Custom N2 Improves Roots

Use of Custom N2, improves roots in green soybeans, edamame, and other crops. Notice  the case study in the final picture, the root on the right has been treated with Custom N2. The root on the right is the untreated control. The treated root is larger and has more offshoots. Its easy to see why this treated plant will thrive and perform better than the untreated plant.

How Bio-fertilizers Help Plants.

In general, biofertilizers take advantage of natural microbe plant interactions. As already discussed, bio-fertilizers help the plant fix nitrogen, solubilize nutrients (particularly phosphorus), and stimulate plant growth. Additionally, biological fertilizers help build organic matter and restore the natural soil nutrient recycling system.

Generally, bio-fertilizers reduce the need for traditional fertilizers and reduce the runoff of fertilizers. This reduced runoff is important as phosphorus and nitrogen contamination of lakes and streams is becoming an important environmental concern.

Importantly, biofertilizers form a symbiotic relationship with plant root systems. These beneficial microorganisms convert nutrients into a form that can be utilized by the plant. Beneficial microorganisms produce a number of plant hormones and plant growth factors that have a very positive effect on plant growth and plant productivity.

Biofertilizers tend to be cost effective compared to traditional fertilizers and a 20-30% costs savings can be seen in some field trials.

Private labeling of our products is available and we can customize a biofertilizer to fit your needs.
