Outline of Final Research Achievements	Research on tropical plantations of sugarcane, palm and cassava was carried out in south Sumatra, Indonesia. We have found that no-tillage increased both litter and soil microbial biomass and diversity, and mulching increased microbial biomass, whereas diversity was decreased by mulching. No-tillage with bagasse mulching gave the similar crop yield of sugarcane with the conventional practice. Material flow analyses were performed in the crop processing factories, biomass residue and wastewater treatment, and the recycling systems such as methane fermentation, composting, beef cattle fattening, and so on. Based on the obtained data and information, a system model to design and evaluate the biomass residue recycle system for the plantation was developed. Environmental impact of plantation and requirements for the disseminating the biomass residue recycle system into the plantation have been clarified through this research.
