Can Trichoderma harzianum be mixed with high nitrogen fertilizer?

You can't. High nitrogen fertilizer will inhibit the growth of Trichoderma harzianum, so it can't be used continuously in soil, because it will lead to the imbalance of microorganisms in soil and affect the growth of crops, so Trichoderma harzianum can't be mixed with high nitrogen fertilizer. Trichoderma harzianum, as a pure microorganism and broad-spectrum bactericide, has antagonistic effects on many plant pathogens through various mechanisms such as nutritional competition, heavy parasitism, cell wall decomposing enzymes and inducing plant resistance, and has dual functions of protection and treatment.
