Energy assessment of the work complex machines with application of fertilizers

Abstract

Technologies and means of organic fertilizers are analyzed in the work. Parameters fields, the distance of transportation and application rates significantly affect the technology of fertilizer application and the selection of the relevant complex machines. On the fields a large area rational use of wide-speed units for organic fertilizer. By using (as bedding) the straw of cereals, part of which 15% by weight of excrement, humidity increases humus, reduced energy costs when loading and spreading, reduced part of the free water, improved sanitary condition of manure storage facilities. Evaluation of machines and systems for operational energy performance conducted. The complex material and energy cost to make 1 ton of fertilizer energy costs are 50 to 80% depending on the distance of transportation. With increasing distance transportation energy costs are increasing much faster than the material. Experimental results show that with the increase in application rates and to reduce the mass of the heap, the quality of the formation the roll increases. Significantly increases the reliability and quality operation of the spreader. Based on the analysis of technological schemes of fertilizer application for medium-sized farms perspective technology is reloading. Reloading technology eliminates the transshipment delivery schemes of fertilizer, which minimizes the loss of nitrogen in the atmosphere.
