ABSTRACT:
The article presents results of studies of late cabbage grown in the four-field intensive crop rotation secured in 1992 on a dark brown soil. The studies have shown that coefficients of fertilizer nutrients in nitrogen ranged 71-86%, in phosphorus 20-21% and in potassium 109-154%. At that a high coefficient in nitrogen (86%), phosphorus (21%) and potassium (154%) was detected in a sample with a double dose of complete fertilizer. With the increase of nutrient removal fertilizer coefficients increased.
