The use of local fertilizers supplemented with Trichoderma koningii Oudem. at no-till vs. conventional tillage of agrochernozem in Southern Ural

Local agrominerals and fertilizers, including marsh plants, which are the waste from cleaning lakes and reservoirs, have definite prospects in preventing soil erosion and restoring fertility alongside with the traditional anti-erosion technologies. Given this, we studied local fertilizers (manure, zeolite, sodium humate) and plant residues (marsh plants, straw) with the addition of (NP)60 and suspensions of microscopic fungus Trichoderma koningii strain IB G-51 ( T. koningii ) when used at no-till (NT) and conventional tillage (CV) of the weakly eroded Chernozem (Mollisol). The effects were estimated based on the key agrochemical properties (humus content, mobile phosphorus, potassium, and alkaline hydrolyzed nitrogen), assay of activity of soil hydrolases and oxidoreductases and the yield of agricultural crops (spring wheat, barley and sugar beet). A three-year investigation was conducted in the Ural steppe zone. Single application of local fertilizers was shown to promote increasing in soil humus content, improvement of nutrient regime, and increment of enzymatic activity and crops yields...
