Agrochemical, physical and chemical indicators of irrigated gray-meadow soils in arid zone of Azerbaijan

The article presents the results of physical, chemical and agrochemical indicators of serozem-meadow soils occupying the largest area on the Shirvan plain. Formed in humid places in the presence and proximity of groundwater to the earth's surface. On the plain, there are also dark, common, light gray-meadow, saline, boggy and other subtypes and varieties of soils. According to the granulometric composition, clay, sometimes sandy loam soils. The agrochemical properties of irrigated gray-meadow soils in the Malbinasi village of the Yevlakh region were studied and the general and assimilated forms of ammonia nitrogen (N-NH4), nitrate nitrogen (N-NO3), and mobile phosphorus were absorbed P2O5, exchangeable potassium K2O in the 0-100 cm soil layer was poorly supplied. Agrochemical studies of agricultural land in the arid zone make it possible to determine the agronomic and economic efficiency of fertilizers used on these lands.
