TOOL FOR CRUSHING GREEN MANURE ON THE SURFACE OF THE SOIL IN ORGANIC FARMING TECHNOLOGY
In the article, the authors discuss the necessity of the mulching layer in organic farming technology and provide substantiation of parameters of a machine for packing and chopping of green manure on soil surface. The purpose of the research is to develop a machine for chopping of green manure on soil surface, which increases productivity and provides proper quality of the technological process. Developing such a machine is a quite urgent problem at present when the use of stubble remains and green manure in aggregate with other factors provides opportunities for increasing the fertility of the soil. When carrying out the research the authors used theoretical and experimental methods based on applying the fundamentals of the agricultural mechanics, the theory of agricultural machines and methods of measurement regulated by normative documents. In the article, the authors present the results of the research that substantiate a constructive-technological scheme of the machine for chopping of green manure and mulching of soil surface. Also the authors present the substantiation of the parameters of a roller with chopping elements that is the main working tool. Besides the authors present the results of experimental research which confirm the theoretical research on parameters of the roller. Based on the conducted research the authors concluded that the developed machine provides quality chopping of green manure and mulching of soil surface in organic farming technology.
