THE INFLUENCE OF THE APPLICATION OF INNOVATIVE TECHNOLOGY ON THE FERTILITY OF SALINE SOILS OF THE SCHULDER MASS AND THE YIELD OF CORN

The article presents the results of work obtained on the saline soils of the Kenzhegara and Bakyrambek farms of the Shaulder massif of the Turkestan region using innovative technology on saline soils. Technology was introduced on 20 hectares of irrigated soils with the support of FAO under the agreement on the project “Integrated management of natural resources in droughtprone and saline agricultural production landscapes in Central Asia and Turkey (CACILM-2)”. This FAO-GEF project is multi-country and its main goal is to widely disseminate and scale up the best technologies and approaches for integrated natural resource management in arid and saline areas of Central Asia and Turkey. The practical implementation of the program was carried out by us to solve the problem of obtaining a harvest of corn on saline irrigated soils. We have compiled maps of soil salinization of 2 peasant farms to a depth of 0-20, 20-50 and 50-100 cm at the beginning of implementation and at the end. It was found that when using this technology, 70.8 % of the soils of the Kenzhegara farm passed into the category of non-saline, and the corn yield increased by 25.5 % and the increase averaged 23.3 c / ha.
The same pattern is observed in the soils of the Bakyrambek farm, where 100 % of the soils became non-saline after the introduction of innovative technology, and the yield increased by 33.1 %. The economic efficiency of innovative technology in the Kenzhegara farm amounted to 127.8 thousand tenge / ha, and in the Bakyrambek farm 124.3 thousand tenge / ha.
