Abstract

The effect of biological soil activation against the background of mineral and organic fertilizers (green manure) on the content of essential amino acids in winter wheat grain was studied. The technique is a pre- sowing application of a consortium of microorganisms (Pseudomonas fluoreiscence, strain AP-33, Azotobacter vinelandii IB-4) and microscopic fungi (Trichoderma harzianum and Trichoderma viridae) using a boom sprayer. It was found that the application of green manure and mineral fertilizers to non-activated soil is accompanied by a decrease in the amount of essential amino acids by 15.7 and 15.6%, respectively, in variants without mineral fertilizers and with ½ of their calculated dose. It has been established that the use of biological soil activation with the incorporation of green manure helps to increase the concentration of essential amino acids in variants with doses of mineral fertilizers 0 NPK and ½ NPK by 8.8 and 14.9%, respectively. An idea has been formed about the role of soil biological activity as a factor influencing not only the quality of agricultural products, but also a factor limiting the level of its productivity. Thus, it was found that the use of soil bioactivation helps to increase the yield of winter wheat by 11.7-17.7%, depending on the type of experiment.
