Abstract

It was found that optimal parameters of soil dehydrogenase, polyphenoloxidase, 2 invertase, urease activities and high crop productivity were observed under Luvisol loamy sand soil supply by mobile potassium at the level of 196 mg kg^-1К О and K application as well as at the level of 288 mg kg^-1К Оand K application. Excess 90-120 2 60-120 of mobile potassium content in soil resulted in reliable depression of soil enzymatic activity, stabilization or reduction of crop productivity.
