The cellulolytic activity depending on soil tillage and influence of forest strip under winter wheat agrocoenoses

Abstract

The aim of the study was to determine cellulolytic activity depending on soil tillage in a long-term crop rotation under winter wheat agrocoenoses. There also were determined the cellulolytic activity in dependence of experimental plots location toward forest strip. The study was carried out at the Didactic Experimental Station “Chetrosu” of the State Agrarian University of Moldova on carbonate chernozem with sandy loam texture. The cellulolytic activity was determined according to the Misustin E., 1978, method based on the principle of cellulose decomposition under aerobic conditions by incorporating linen tissue in the 0-30 cm soil layer. The research has shown that soil cellulolytic activity is characterized with very low index level under both Plowing and No-till variants during June of 2017-2018 crop year - that registered dry weather conditions. The presence of forest strip near the crop land has revealed its beneficial influence on soil moisture preserve that facilitated cellulolytic activity on the plots located besides the forest strip under both soil tillage variants. It has been confirmed that forest strip (shelterbelt) form a microclimate with benefits for crop land.
