Description
This study was aimed to assess the effect of effective microorganisms (EM) application on the composting of sawdust with cow dung and to evaluate the quality of compost. Four treatment piles were investigated in this study, in which two piles (sawdust and cow dung ratio of 1:1 and 2:1) were applied with EM and another two piles (sawdust and cow dung ratio of 1:1 and 2:1) were treated without EM, as control. Each treatment was carried out once with a duration of ISO days of
composting. Changes in temperature, pH, total organic carbon, height of compost piles, moisture content and C/N ratio showed that decomposition of organic matter occurs during 120 days of composting in EM treatments and 1SO days in control treatments. It was also found that the composts produced from sawdust and cow dung ratio of 2:1 possessed better characteristics and higher nutrient values than those produced from raw materials ratio of 1:1. The application of EM in composting increased the macro and micronutrient contents of compost. The following parameters support this conclusion: compost applied with EM has more N (0.63%), P (0.15%) and K (0.53%) contents compared to compost without EM in which N (0.56%), P (0.12%) and K (0.49%). This study suggested that the application of EM is suitable to shorten the 'composting process and increase the
mineralization of compost. The final resultant composts indicated that they were in the range of the matured level and can be used without any restriction.
