Kovalenko O. Phosphates transformation in meadow-chernozemic soil in Forest-steppe of Ukraine de-pending on fertilizers application

Object of researches: phosphatic mode of black meadow-earth carbonate soil; loud speaker of maintenance of mobile connections of nitrogen, phosphorus and potassium in soil under a winter wheat, maintenance of staples feed elements in the plants, productivity and quality of winter wheat corn. Establishment of maintenance and composition organic and mineral phosphorus compounds in meadow-chernozemic calcareous soil at the long-term fertilizers ap-plication, calculation of phosphorus balance in a crop rotation and prognosis drafting of changes maintenance of element in soil, was the purpose of researches dynamics of phosphates sorbtsii and de-sorbtsii. Methods of researches: field, laboratory, statistical. A scien-tific novelty consists of establishment of influence of the long-term fertilizers application on maintenance of phosphorus connections in soil and their transformation in years with the less saturation of crop rotation by the fertilizers. The calculation of phosphorus balance in a crop rotationis produced. The volumes of phosphorus absorption on the type of physical and hemosorbtsii are set. The basic results of researches are applied in industry. Industry - agricultural chemistry.
