There are several species of Trichoderma fungi that are used as biofertilizers. Trichoderma has many benefits in farming, agriculture and home gardening.
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 virulent plant symbionts. In other words, they form a symbiotic, or mutually beneficial, relationship with plants. This symbiotic relationship is what biofertilizers try to exploit. The idea is simple, by adding more Trichoderma the plant receives more benefit.
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.
Increases plant tolerance to environmental factors like drought and high soil salinity. T. harzianum increases mineral absorption.
When it is used as a seed treatment, increases the germination rate in a number of crops.
This Trichoderma 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.
Known to increase the growth of seedlings and secretes seed germination factors.
Normally found in cooler climates, this Trichoderma conveys all of the benefits associated with the other Trichoderma fungi.
For many soils, some type of combination of the above methods may be the best option.
