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.
