Pavlyk R. Agrochemical efficiency of the use of polymyxobacterin along with long-term application of fertilizers to corn for silage on the meadow-chernozemic carcareous soil in the right-bank Forest-Steppe

On the basis of the studies found that prolonged use of organic and mineral fertilizers in crop rotation helped to improve soil nutrient regime and increase its fertility, increasing the content of mineral nitrogen, phosphorus and rolling exchange of potassium in the plow layer and pidornomu alkali-carbonate chernozem soil. The effect of prolonged use of fertilizers in crop rotation on fitometrychni performance, dynamic content elements in power plants and the formation of yield and quality of corn silage proved positive fosfatmobilizuyuchoho influence microbial drug polimiksobakteryn the dynamics of content batteries in soil, plants and the yield of corn for silage. Revealed the nature of the impact of prolonged use of fertilizers on the content and mobility of trace elements and heavy metals in soil and their flow to the plants. Adapted method for determination of nitrogen status of plants to adjust their conditions of supply and determine the need for nitrogen fertilization during the growing season. It is determined agrochemical, energetic and economic efficiencies of applyed mineral fertilizers and aftereffect of organic fertilizers and application of polymyxobacterin to corn for silage on the meadow-chernozemic capcareous soil.
