EFFECT OF DIFFERENT LAND-USE TYPES ON THE HUMUS STATUS AND AGROCHEMICAL PROPERTIES OF IRRIGATED LIGHT SEROZEM SOILS IN THE ARID ZONE OF KAZAKHSTAN (A CASE STUDY OF THE KYZYLORDA REGION)
Light Serozem soils constitute the principal soil resource supporting irrigated agriculture in the arid regions of southern Kazakhstan. Their inherently low organic matter content, rapid mineralization rates, and susceptibility to secondary salinization make them highly sensitive to changes in land use. Therefore, asse...
