SOIL-ECOLOGICAL CONDITION OF FURROW AND DRIP-IRRIGATED SOILS SOWN WITH SUGAR BEET IN THE BAYZAK DISTRICT OF ZHAMBYL REGION

The article describes the ecological state of the soil under conditions of soil and drip irrigation sown with sugar beets. The studied irrigated soils have a predominantly light sand grain size distribution. Analytical studies show that of 13.8-51.5%, the majority of microaggregates are in the large dust fraction, from 57.7% to 12.5% - in fine sand, the rest are fine dust and sedimentary fractions. Humus results showed low and very low soil humus: soils are moderately provided with mobile forms of nitrogen, low phosphorus and potassium. The soil of the study object is slightly alkaline and alkaline. The results of the soil classification of erosion hazard showed that the soil of the site under conditions of rusty irrigation belongs to hazard class 2, i.e. the erosion hazard is weak (the output of the solid part is 4.1-5.3 t/ha per year.
