Environmental Impacts of Farm-Scale Composting Practices

摘要: Because of its agronomic benefits, farm-scale composting is an efficient means recycling agricultural waste. Composting process aerobic degradation fresh organic matter in mature compost. Nevertheless, according to the literature, may induce some environmental problems. The impacts will be described, along with assessment practices which play a major role pollution. main components potentially affected by pollution are air and water. Various gases released composting, such as NH3, CH4 N2O, can impact quality therefore studied because they all have controlled management. effect on water evaluated considering loss NO3 -, NH4 +, compounds PO4 3-. Technical evaluation criteria for determined from physical chemical characteristics raw materials, use additives, turning method frequency duration operations. Regarding water, weather conditions at beginning operation, location heap, protection against rain, addition during process, covers recovery leaching runoff also taken into account. two control are: choice material influences gas emissions high losses runoff.
