Kozyrev V. Influence of complex melioration activities on productivity of soybeans under irrigation weakly mineralized waters

The object of research - the processes of formation of physical and chemical properties of dark brown soil on soybean crops; water consumption dynamics. The purpose of research - to establish the influence of the complex melioration activities measures the nature and parameters of changes in the main indicators of fertility of dark chestnut soils and productivity of soybean under irrigation weakly mineralized waters in Southern Ukraine. Research Methods - field, laboratory, billing, statistics. The research results - for the theory: For the first time in the conditions of the south of Ukraine has developed a set of agro-reclamation measures that contribute to maintaining the fertility of dark chestnut soils, prevention of their degradation, maintaining a satisfactory ecological and agro-reclamation state and obtain high and stable yields of soybeans under irrigation weakly mineralized waters. To practice: On the basis of research in the interconnected system "irrigation water - soil - plant" is given a comprehensive evaluation of the impact of the factors that have been studied on soy melioration activities performance and condition of the soil. Scope of use - agricultural enterprises of the south of Ukraine.
