This study was performed to evaluate the composting process of agricultural wastes using the solid state fermentor at the general optimum composting conditions. The changes of physico-chemical and microbiological flora in the reactant during the composting time were investigated. The results were summarized as follows :
From the results of proximate composition analysis of fermentation enzyme, the content of moisture, crude ash and total carbohydrate were 2.29, 67.57 and 22.69%, respectively. The number of thermophilic bacteria and actinomycetes in the enzyme were 2.6×10^(4) and 4.1×10^(5) respectively. During the composting time, the content of moisture in all wastes was decreased but acorn waste was not changed. The generation of maximum CO_(2) was in the range of 1,500∼10,000ppm after 12∼36hrs of composting time and then was gradually fallen. The C/N ratios of the Injin murgwort, arrow root and mushroom media waste were increased, but acorn waste was decreased. The contents of inorganic components(P_(2)O_(5), K_(2)O, CaO, and MgO) in the Injin murgwort, arrow root and mushroom media waste were a little decreased, but acorn and hole wastes were increased. The changes of thermophilic bacteria, in the Iniin-murgwort and arrow root waste showed big diversity while acorn and hof waste were slowly decreased.
However the population number of thermophilic actinomycetes in the acorn waste was increased until for 24 hrs and then gradually decreased. The population number of thermophilic bacteria and actinomycetes showed not much difference.
