THE BIOLOGICAL EFFICIENCY OF CROP ROTATIONS AND GREEN MANURES TO IMPROVE THE PRODUCTIVITY OF IRRIGATED LANDS

Agricultural production at the present stage of development requires a systematic and widespread increase in the fertility of irrigated lands of Kazakhstan. Therefore, the issues of improving the ecological situation in modern agrolandscapes, maintaining and reproducing soil fertility in them and increasing the productivity of crops have become particularly relevant at present. There was a need to create not only environmentally sustainable and safe technologies and techniques, but also the maintenance of farming systems as a whole. Increasing volumes of anthropogenic impact on the environment pose a challenge for scientists to assess and develop preventive measures and reduce negative consequences. The aim of the research is to develop effective ways to improve the basic conditions for the reproduction of soil fertility, increase the productivity of irrigated lands and obtain environmentally friendly products in a system of biologized crop rotation. The results of studies on improving the basic conditions for the reproduction of soil fertility, increasing the productivity of irrigated lands and obtaining environmentally friendly products in a system of biologized crop rotation are presented. The results obtained indicate that biologized crop rotations for rotation in the soil develop a positive deficit-free balance of humus in the soil. This was achieved mainly due to the cultivation of perennial grasses, legumes, and the use of biologization agents.
