Kоstiuk M. The influence of the long-term using of fertilizers and lime on agrochemical properties of the light-grey forest surface-gley soil of the western Forest-Steppe

Object - physical and chemical processes and agrochemical properties of light grey superficially - glened soil, its stability to anthropogenous loadings, orientation and intensity of agrochemical transformations which occur in soil under long fertilizers and lime application and their influences on quantitative and quality indices of a maize yield formation. Methods - field, vegetative, laboratorial and chemical, statistics-mathematical. Theoretical results - appropriatenesses and regional features of influence of various systems of fertilizers and liming in a crop rotation on change of agrochemical properties and buffer capacity of light grey superficially - glened soil and productivity of green weight of maize on a silo are determined. Practical results - the rational system of fertilizers, manure and lime application is scientifically proved basis of the expanded reproduction of light grey soil fertility. Novelty - system of fertilizers application in a crop rotation which provides improvement of agrochemical parameters and increase of light grey superficially - glened soil's fertility and obtaining of high maize yields is substantiated. For the first time in conditions of the western Forest-steppe parameters of buffer characteristics as high - informative criteria of an estimation of basic properties that will form a basis of development and construction of light grey superficially - glened soil's model of fertility are investigated and will enable conducting sources economizing agriculture with application of optimum - necessary rates of fertilizers and lime. Degree of introduction - results of researches take root in pilot farms of Institute of agriculture and animal industries of the western region UAAS and СФК named after I.S. Kil'gan of the Lvov area. Branch - an agricultural production.
