Analysis of energy efficiency of production of compost from manure of cattle

Organic fertilizer is a source of necessary for agricultural plants macro-, microelements and carbon dioxide. Due to their gradual mineralization nutrients enter the during whole period vegetation. In production, in particular organic fertilizers, main factor determining profitability effective use energy. The aim work was carry out analysis energy efficiency production compost vermicompost from manure cattle. Research materials data technical information, scientific literature technologies composting vermicomposting cattle, Internet information results own research. Energy producing animal waste determined by method direct cost It that at great degree, using diesel fuel (98.3%). A small percentage occupied workers (1.7%). established, cattle consumption energy, human accounts 0.39±0.08 MJ/kg. most energy-intensive processes are mixing watering his water, which spent 0.17±0.05 Less energy-intensive: transporting formation stacks (0.06±0.01 MJ/kg); filling container with water its (0.07±0.01 covering stacks, drying packing (0.11±0.02 MJ/kg). When preparing 1 kg substrate later vermicultivation (diesel human) amounted 0.16±0.04 MJ. During process vermicultivation, 0.41±0.08 vermicomposting, more on 0.23±0.07 such as: vermi bed colonization vermiculture separating worms biohumus (0.07±0.01MJ/kg); (0.05±0.1 At vermicompost, 0.57±0.12 MJ, worth 0.87±0.12 UAH. fertilizers through composting, reduced an average 31.6% 26.4%.
