ABSTRACT DAIRY manure was composted in a batch type enclosed composter without regular mixing for 7 days. The maximum decomposition was obtained in the range of 65 to 70 C at initial moisture content as between 55.5 and 64.6% (w.b.), initial pH value 7.8 to 8.3 and 0.87 to 1.07 L/min-kg per volatile matter of air. Carbon dioxide content in effluent gas was around 4.7 to 7.5% per volume at 68 C. Stabilization time for the plateau temperature (70 to 75 C) must be related to the aeration rate and moisture content in compost mass. The mixed manure with straw was a valuable acid soil conditioner.
