- Аннотация: 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. Thus, the increase of humus content in the 0-30 cm soil layer for 3 years is reliable for both types of tillage except the cases when zeolite and sodium humate were applied. These values increase by 3.5-5.6 % for NT, and by 1.8-4.1 % for CV as compared to the control. The soil phosphorus reserve increases from low to medium level due to manure and crop residues with mineral fertilizers added at no-till, whereas at CV a significant increase is observed due to the manure only. Potassium content elevated significantly, from 32 to 45 %, only at application of manure and marsh plants with the addition of (NP)60 and T. koningii. The content of alkaline hydrolyzed nitrogen varies in a narrow range, and the significant increase is observed only at no-till with manure and marsh plants. Soil enzymatic activity is higher when manure and plant residues are introduced, in contrast to variants with sodium humate and zeolite. Among enzymes, protease and polyphenoloxidase show the closest correlation with agrochemical properties (r = 0.53-0.75, p < 0.05). The change of agrochemical properties and enzymatic activity of soil is more apparent in 0-10 cm layer under NT and in 0-30 cm layer under CT. The profitability of fertilizers under NT is higher, as compared to CV, only in arid conditions. Biologization of agricultural technology by introduction of the microscopic fungi T. koningii IB G-51 causes the faster humification of the marsh plants than the straw that must be especially accounted for at NT. The effect of marsh plants + T. koningii on soil properties is commensurate with that of manure. © 2018 Russian Academy of Agricultural Sciences. All rights reserved.
