摘要：Research study was carried out during 2006-07 at the University of Guyana campus to produce vermicompost on a large scale and assess the physicochemical changes that occur during the process of biodung and vermicomposting, as well as to assess the quality and quantity of the vermicompost harvested. The attempt was made to solve the problems of disposing organic waste by biodung composting and vermicomposting processes. The temperature changes in the predigestion of organic matter showed effective anerobic and aerobic decomposition process. The temperature of the biodung units rose to a maximum and then declined gradually to a constant temperature, bringing about reduction of organic waste free from harmful microbes. The results indicated that the vermicompost is highly rich in nutrient and the percentages of these nutrients in the compost vary as the process proceeded until their ideal concentrations for the promotion of plant growth reached. Vermicomposting of the water hyacinth+ grass (T2) resulted in high productivity of vermicompost followed by water hyacinth (T2) grass (T1).
