Head Vasily Kharchenko, Registration Date 22-06-2006 Organization Chernihiv Institute of Agroindustrial Production of the Ukrainian Academy of Agrarian Sciences popup.description2 Object of researches - agricultural cultures, soil, fertilizing. The purpose - to elaborate technology of usage phosphorites as phosphoric fertilizings under agricultural cultures. As a result of the conducted researches is established, that on soils the phosphorites increased productivity of barley, winter wheats and corn on 15-25 of % Agrarian-ekological by an estimation is established, that usage of phosphorites even for high doses (180 kgs / га д. In.) can not essentially influence on зpollution of soil high-gravity metal and fluorine. Thus the acidity of soil on 0,2-0,4 units рН was lowered, the contents of nitrates in a nem more than for 2 times and movable phosphorum on 1,5-3,5 мг/100 г of soil was increased.
