the temperature of pile was monitored manually three times a day by thermometer, which was plugged into composting pile at a depth of 15 cm. from the surface of central part piles . sample were withdrawn from three measured point evenly placed at about 10 cm. distances from the edge of the reactor and at about 20 cm distances between two adjacent measured point, and characterized for the following parameters. moisture contour content was determined after dry-ing at 105 c for 24 h. 1 g. sample and 10 ml deionized water were mixed, stirred up, left to settle for 10 min. and measured ph by a ph electrode.
