Outline of Final Research Achievements

This research aimed to reduce burden on environment by applying biochar (BC) to agricultural system in the Mekong Delta. BC production technique applicable to small scale farmers was developed. Application of BC to paddy field resulted in reduction of emission of greenhouse gases (methane and nitrous oxide) without negative effect on rice yield. Application of BC and compost to a soybean field resulted in increase of the yield and stimulation of soil enzyme activities. Long-term nutrient supply to soybean due to stimulated enzyme activities is considered to be attributable to increasing the soybean yield. Diarrhea of swine, which is prevalent in the Mekong Delta, was prevented by feeding a mixture of feed and BC because BC is capable to absorb pathogens. For above results, application of BC effective and practical to reduce greenhouse gases emission, to increase crop yield, and to reduce emission and the amount of anitbiotics administered to swines.
