Harvest residues bio-treatment as a soil incorporation improvement

Abstract

The aim of this work is to determine the influence of biological preparation for cutting and breaking mechanical characteristics of overwintered winter wheat and oilseed rape plant residues, depending on biological preparation action period and compare research results with the same researches obtained in the natural conditions. Experimental research of physical-mechanical properties of plant residues were carried out in 2013-2014 at laboratories of Institute of Agricultural Engineering and Safety of Aleksandras Stulginskis University, using experimental research machine „Instron 5960“. The results of experimental investigations showed that forces required for termination and cutting of plant residues are lower, using biological preparation than without it. The time period over which plant residues are exposed in natural climatic conditions and/or biological preparation affects breaking and cutting properties of plant residues.
