The article provides an overview of agrochemical studies carried out on irrigated light chestnut and brown semi-desert soils of the Saratov, Volgograd regions and the Republic of Kalmykia. It is noted that in stationary experiments carried out in these regions, the influence of long-term use of mineral fertilizers on the transformation of agrochemical properties and the productivity of crop rotations of various specializations was studied. In numerous short-term experiments, the optimal types, doses and timing of mineral fertilizers were determined for the cultivation of cereals (spring and winter wheat, corn and sorghum for grain), legumes (soybeans, chickpeas), forage crops (Sudan grass, sugar sorghum, alfalfa, cereal mixtures for estuaries), technical (camelina, mustard) and vegetable (tomatoes, onions) crops.
