Gavriluk V. Аgroecological chemistry estimation of phosphorite-bearing of agroores Western region of Ukrain (on the example of local granular and concretionary phosphorites)

Object - laws of processes of interaction of local phosphorites of granular and nodule types with soil at its application in a part of a crop rotation. The purpose - to determine the law of local granular and nodule phosphorites influence on optimization of a nutritious mode and bioproductivity of sod lightly-podzolic soil to prove agroecological criteria of its application. Methods - general scientific and special. Theoretical results - law of the phosphorus content change by local phosphorites applying is revealed, in arable and plough-pan layer of soil in view of different methods of its mobile forms definition. It is determined, that local phosphorites do not cause accumulation of heavy metals in soil and have high radio-protection properties. Practical results - ways of crops fertilization by local granular and nodule phosphorites-contaning ores are carried out. Novelty - effective, economically favorable and ecologically safe norms of application of local phosphorites, its influence on size andquality of a yield of a potato, summer barley and green weight of clover are carried out. The agroecological, economic, and energetical estimation of application efficiency of local phosphorites-contaning agroores is determined. The degree of introduction - efficiency of use of local phosphorites-contaning agroores on sod lightly-podzolic gley sandy soils in zone of Polesye of the Western region of Ukraine is proved. Sphere - an agricultural production.
