Abstract
The aim of the study is the selection and analysis of the most relevant fertilizers–meliorants, assessment of their application in the reclamation of irrigated agricultural land. The research was based on experimental and theoretical methods of analysis, generalization, comparison of data. The carried-out characteristic of the fertilizers–meliorants used for reclamation of agricultural lands allowed to allocate, complex fertilizers–meliorants which include industrial waste and natural sorbent–meliorants. Non-traditional fertilizers–meliorants created on the basis of sewage sludge with the addition of natural sorbent–meliorants are analyzed. The formulas for determining the optimal doses of fertilizers–meliorants on the agricultural landscape with different intensity of degradation processes, which allow minimizing the technological processes with greater economic efficiency, are obtained. In areas with low intensity of degradation processes, 100 g/m2 (or 1 t/ha) should be applied, for the average — 350 g/m2 (or 3.5 t/ha), for high intensity of degradation processes, 850 g/m2 (or 8.5 t/ha) should be applied. Application of fertilizers–meliorants in the reclamation of irrigated agricultural landscapes is necessary, first of all, in the restoration of soil–forming factors.
