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.
