Abstract

Different microorganisms applied singly or in combination were employed in composting rice straw in six (6) compost pits, 2 meters long, 1 meter wide, and 0.8 meter deep.. In pit A, rice straw was used as the only composting material without any inoculation. In pit B, thirty (30) kilogram cow manure was added to rice straw. In pit C, Trichoderma viride and Cytophgga sp. were inoculated to the rice straw. In pit D, rice straw was inoculated with T. viride, Cytophaga sp. and Beijerinckia sp. (Luisiana train). Only Beijerinckia sp. was incorporated to the rice straw in pit E. Eukomit, a commercial preparation of mixed organisms, was applied to the rice straw in pit F. Temperature readings were obtained three times a day for forty five (45) lays composting period after which samples were taken for the determination of exchangeable ammonia and organic matter content. Maximum temperatures averaging to 40 C were recorded within the 4th day after the start of piling. High temperatures were observed during the first three weeks of piling which was then followed by a sudden drop in temperature and moderate fluctuation during the later half of the composting period.
