INFLUENCE OF AGROTECHNOLOGIES ON SOIL HEALTH IN NORTHERN KAZAKHSTAN

Abstract

Fertile and healthy soil is a productive, environment-forming, bioresource ecosystem of the Earth. Soil health can be considered an integral part of fertility, the most important functional biological category. The purpose of these studies was to study the effect of organic backgrounds with plowing layers of perennial grasses into the soil, on increasing the input of organic matter into the soil in the form of plant residues, which will preserve the problem of reproduction and preservation of fertility and soil quality. The study was carried out in comparison with a traditional background where mineral fertilizers were applied. In soil samples, the content of organic matter and its labile fractions, as well as the content of organic pollutants (microelements and heavy metals) were determined. The content of organic matter and its labile fractions on an organic background was at the same level in comparison with the traditional one, varied over the years depending on the conditions of the growing season. The accumulation of trace elements, heavy metals also differed by year and by variants, but the results obtained did not exceed the recommended maximum permissible concentration.
