| Abstract |
Composting methods have resilient influence on spot differences in the physical and chemical characteristics of compost maturity. In the current study three ventilation methods for composting were evaluated, local turners, manual turning using hand shovels, and natural ventilation, the processes were examined between a week intervals up to 22 weeks. The gradual changes in physicochemical characteristics (temperature, pH, moisture content and C: N ratio) related by compost stability and maturity were studied and compared, the results showed that, the nitrogen level increasing is highly influenced by temperature degree, where in mechanical ventilation and manual turning were higher than in the natural ventilation . The optimum level for compost stability and maturity parameters like moisture content, C\N ratio, pH, particle size, odor, and composting time were reached earlier in mechanical ventilation process as compared to manual turning ventilation processes due to good and enough ventilation. The results of the current study will improve the production method and the compost quality. The final investigation results indicated that, using mechanical turning give best compost characteristics compared with natural or manual ventilation. Where the pile 3 was aerated by the mechanical turning once a week has optimum properties of compost especially in C\N (22/1) and pH (7.5) beside an average particle size (6mm).
