The fertility indices of the main soil types of the Tersk-Sulak lowland used in irrigated husbandry are considered. Intensive anthropogenic impacts on irrigated soils result in a decrease in their fertility. Agriculture is conducted with a negative balance of humus and nourishing elements in handle soils. The dependence of productivity on the humus content, adsorptive capacity, granulometric composition and extent of soil salinization is established.
