Dzhybo A. Evolution of physico-chemical and agrochemical propeeties of the typical chernozem soil during its extensive and intensive agricultural use

Object of research-typical chernosem The purpose of research-establishment of general laws and features of fertility's formation of typical chernosem at different agricultural intensification levels. The methods of research-research are carried out in long field experience, analytical works and the mathematical processing of the received data is executed with application of modern methods. Theoretic results- the basic directions of change parameters of effective fertility ensuring maximal chernosem's efficiency . Novelty-the carried spent research have allowed to establish major importances of parameters of evolution of typical chernosem in conditions of different levels intensity of agricultural use. Degree of introduction-the results of research can be used in pratice of agricultural manufacture with the purposes to forecast of fertility's change of chernosem soil and their efficiency. Sphere-agricultural manufacture.
