Puzniak O. Renewal of fertility of soddy-podsolic sandy soils' with toxic indications

Object - dynamics of microbiological, physical and chemical, and agrochemical properties of soddy-podzolic sandy soil with toxic sings. The purpose - an establishment of ways of neutralization of soddy-podzolic sandy soils toxicity, improvement of microbiological, physical and chemical, agrochemical properties under long-term action of various kinds and systems of fertilizers, and as consequence - increase of efficiency and quality of crops' yield. Methods - general scientific and special. Theoretical results - influence of various kinds and forms of fertilizers, their ratio and ways of application on a degree of toxicity of soddy-podzolic sandy soil and a role of its physical and chemical, agrochemical and microbiological properties in elimination of this phenomenon is determined. Practical results - for the first time are developed recommendations for updating of soils' fertility with toxic sings and to increase of agrophytocenosises' efficiency in a zone of the Western Polesye. Novelty - the reasons of toxic sings occurrence in soddy-podzolic sandy soils in Volynsk Polesye for the first time are proved. A degree of introduction - recommendations are developed and their introduction in economy of Kovelsky, Lutsky, Rozhishchensky districts of the Volynsk area on the 200 hectares is carried out. Sphere - an agricultural production.
