| Abstract | ||
| The aim of this study is to determine the influence of three aeration methods in compost production and quality. The studied treatments were: (natural aeration, manual turning using hand shovels, and mechanical turning using self propelled turning machine) with two agitation rates used once and twice a week. The final properties of the produced compost were different in M.C., C/N, pH, particle size, odor, and time of composting. Generally, the results showed that, using an agitation method (manual or mechanical) afford good quality of compost in a short composting period compared with the natural aeration. The final investigation results indicated that, using mechanical turning may give best properties of compost compared with natural or manual aeration. The heap 4 that was aerated using mechanical turning once a week has optimum properties of compost especially in C/N (23/1) and pH (7.5) beside an average particle size (12mm). | ||
