The subject of research is adaptation and clarification of fertilizer irrigation of corn and chemical melioration of irrigated chernozems, factors affecting the formation of the water and nutrient regime of the soil, moisture availability of corn under fertigation. Regularities of the salt regime, changes in physicochemical and agrophysical properties of irrigated soils under the influence of chemical meliorants. Study of regularities of formation of soil moisture reserves under winter wheat crops in critical and spring-summer periods for the smallest calculation period. The purpose of the research is to develop ecologically balanced technologies for land reclamation, rational technologies for the cultivation of rural areas. crops under irrigation conditions, formation of sustainable ecologically balanced agrolandscapes in the Northern Steppe of Ukraine. To study the optimal norms, methods and terms of application of mineral fertilizers and chemical meliorants under irrigation conditions. To compare the methods of application, terms and types of mineral fertilizers, including liquid complex fertilizers, application doses of phosphogypsum under the intensive technology of growing corn for grain under irrigation conditions. To assess the agro-ecological condition of soils that have been irrigated for a long time with mineralized water; to improve the existing measures to reproduce the fertility of irrigated soils by means of chemical land reclamation. To assess the current technical condition of the main structural elements of the Kielce irrigation system in the Dnipropetrovsk region. Product Description popup.authors Hapich Hennadii V.
