INFLUENCE OF CULTIVATION METHODS ON SOIL FERTILITY

Abstract

In Kazakhstan, there is enough land in desert and semi-desert regions that can be used for growing crops. Therefore, the current urgent problem is the development of new technologies for the development of such lands, as well as the development of favorable and effective research methods. When preparing crops on which agricultural crops are cultivated: it is necessary to fully study the climatic conditions of the studied territory, the reclamation state of the soils, the geomorphological location, agrobiological and economic conditions. At the same time, agrotechnical measures used in crop cultivation should have a positive effect on the fertility of arable soils in accordance with climatic conditions, i.e. to preserve and increase the fertility of cultivated soils. One of the conditions for obtaining a stable, plentiful crop in crop rotation is the optimization of tillage methods.The article presents the results of the conducted research on this issue. The research was carried out on unsecured rain-fed lands in the farm "Akzhar" in the Bayzak district of the Zhambyl region, on ordinary gray-earth soils with a humus content of 1.0-1.2% in the arable layer, on 5 full grain crop rotations. In field experiments, the influence of the traditional method of tillage and the method of flat-cutting on soil fertility used in the specified region was studied.
