EFFECT OF MINERAL FERTILIZER AND AFTEREFFECT OF PHOSPHORUS AND POTASSIUM FERTILIZATION ON CROP PRODUCTIVITY AND ENZYMATIC ACTIVITY OF LUVISOL LOAMY SAND SOIL

Abstract

Environmentally acceptable level of organic substances mineralization (142 %) and high crop rotation productivity (56.7 c f.u./ha) were observed as a result of annual application of N67,3P40K85,7. The introduction of N67,3, as well as combinations N67,3K85,7 and N67,3P40 resulted in surplus enhancement of organic substances mineralization (169 %, 164 %, 167 %) compared control treatment (100 %).
