Economic problems of reproduction of fertility of soils

Abstract

The purpose. To study contemporary state of fertility of soils in Ukraine, to determine basic problems of reproduction of effective fertility and to offer ways of their solution. Methods. Dialectic method of scientific knowledge, analysis and synthesis, system generalization. Results. Contemporary state of fertility of soils as to the content of humus and basic nutrients is analyzed. The causes of level recession of fertility of soils of plowlands are specified, ways of raising economic efficiency of measures on its preservation and reproduction are offered. Conclusions. For preservation and increase of fertility of soils which provides high and stable yields of crops it is necessary to optimize entering of all nutrients of plants in order not only to compensate their removal with crop, but to fill up the content of humus and mobile forms of nutrients in soil.
