Abstract

The article presents the results of research to assess the effect of drip irrigation on the agrochemical and agrophysical properties of light chestnut soils, as well as on the formation of yields of major crops in the foothill zone in Ili Alatau, Kazakhstan. The objects of research were winter wheat, soybeans and corn cultivated in irrigated crop rotation. In the course of field experiments, we studied changes in the density of soil composition, the content of agronomically valuable and durable aggregates, as well as the dynamics of easily hydrolyzable nitrogen, mobile phosphorus and exchangeable potassium during the growing season. It has been established that the use of drip irrigation improves the structural condition of light chestnut soil, increases the proportion of agronomically valuable aggregates and optimizes agrophysical parameters without exceeding the permissible values of the density of addition. It is shown that the maximum values of nutrients in the soil are observed in the middle of the growing season, and by the time of harvest, their content decreases due to active absorption by plants. With optimal agrochemical parameters, high yields are achieved: winter wheat: up to 5.5 tons ha-1, soybeans:  up to 4.7 tons ha-1 and corn: up to 17.2 tons ha-1.
