HUMUS STATE OF TYPICAL BLACK EARTHS OF THE CHERKASY REGION LEFT-BANK DISTRICTS AND IT’S FERTILITY RECREATION WAYS
Abstract
It is showed that in the modern conditions of management in default of stock-raising and manure indemnification of elements of feed takes place due to uncommodity part of harvest, that is considered as biologithation of crop rotations. In 5 field crop rotations with a pea and herbares without top-dressing returning all uncommodity part, provides complete indemnification of macroelements feeding on potassium, and on nitrogen and phosphorus balance was negative. At top-dressing in uncommodity part of harvest there were sufficient quantities of elements of feed for achieving of positive balance on nitrogen and phosphorus, and at the average to 1 ga of crop rotation were recovered: 22 kg of nitrogen, 33 kg of phosphorus and 102 kg of potassium.
