Rational measures of agromelioration on grey soils

Abstract

In the conditions of grey soils in the south of Kazakhstan, the soil is degraded due to irrational use of irrigated land and non-compliance with agro-reclamation works in its order, as well as excessive irrigation of medium-saline soil, it negatively affects crop yields. In addition, on medium-saline soils, winter plowing is carried out only to a shallow depth of 30-32 cm. Mainly on grey soils, with timely and intensive soil treatment, it is preferable, since the degree of bulk mass of gray soils in a stable indicator is 1.28-1.30 g/cm3. If agrotechnological measures are carried out incorrectly, i.e. it affects the increase in soil density and its salinization, which negatively affects the growth and productivity of agricultural crops. In conditions of decreasing soil fertility, scientists of our scientific institution have carried out experimental work to identify the effects of effective agro-reclamation measures on irrigated saline lands, based on the rational use of irrigated agriculture in the south of Kazakhstan. The first issue that hinders the development of agricultural crops and the regulation of the condition of the rooting layer of plants in the soil is soil salinization and measures to combat them, since this issue is very relevant in conditions of increasing irrigated agriculture intensity.
