ENZYMATIC ACTIVITIES OF ERODED LUVISOL LOAMY SAND SOILS ON MORAINE LOAM

Abstract

Steadily depressions of hydrolytic enzymes activities were observed under geomorphologic profile of Luvisol loamy sand soil on moraine loam: compared watershed the invertase activity of medium eroded soil was reduced by 14-24 %, severely eroded soil - by 37-46 %; the urease activity of medium eroded soil was reduced by 13-20, severe eroded soil - by 29-37 %. Oxidized enzymes activities depressions under geomorphologic profile were less significant: on severely eroded soil the reduction of polyphenoloxidase activities varied in diapason of 7-14 %, peroxidase activities - in diapason of 14-21 % compared watershed.
