Outline of Final Research Achievements

We tried to create the soil management technology which used biochar to expand low environmental load agriculture in the tropical developing zone. As the biomass resource, we used the rice husk and Siam Weed.
The possibility that the application of biochar improves soil fertility and increases a yield was suggested. However, the effect depends on soil types. When giving much, the yield sometimes decreases. It is necessary to establish the guideline of application of the biochar.
On the one hand, there was a big effect in the yield increase to the mixing biochr of Siam Weed and the compost. However, because Siam Weed had strong allelopathy obstruction, it proposed to use Siam Weed as the biochar after carbonizing to suppress the obstruction.
