Abstract
The article provides an interpretation of the agroecological characteristics of irrigated grass-gray soils of the Mil-Mughan economic region and provides extensive information about the physicochemical properties of these soils. Based on studies conducted on irrigated meadow-gray soils, the following results were obtained: the genetic layer of soil 0-55 cm was washed away from easily soluble salts, the humus content in all other genetic layers was 0.3-2.1%, total nitrogen 0.11-0.20%, absorbed bases total 18.0-23.0 mg-eq., physical clay (<0.01 mm) 44.0-65.0%, silt particles (<0.001 mm) 18.0-24.0%, density 1.18-1.32 g/cm3, nitrate nitrogen (N/NO3) 3.0-14.0 mg/kg, ammonia nitrogen (N/NH3) 3.0-20.7 mg/kg, C:N — 6.0-7.0, hygroscopic moisture 9.1-4.6%, CaCO3 8.0-17.0%.
