EFFECT OF FERTILIZER AND SOIL CULTIVATION SYSTEMS IN SHORT CROP ROTATION ON NUTRIENT REGIME OF TYPICAL BLACK SOIL

Full Text:

Abstract

Results of researches of efficiency of the organic (green manure, post-harvest residues) and mineral (moderate rate) fertilizers in short-term rotation on the background of plowing and surface soil treatment are given. It is established that significant changes of humus content in 0-30 cm soil layer has not occurred. In general, for the four-year crop rotation period a content decrease of alkali-hydrolysable nitrogen, mobile forms of phosphorus and potassium in the soil is observed.
