Biochar converted from the biomass then applying to soil to improve crop productivity is not a new agricultural technique in the world. Aiming to let farmers know about the benefit of biochar, then expanding biochar utilization in large scale, a field experiment was conducted at Itoshima, Fukuoka city, Japan, in which three root crops namely sweet potato, carrot, and radish were selected and cultivated at three level of bamboo biochar amendment 0% (control), 2% and 4% per soil surface weight (about 30 cm soil depth is expected). Crop's yield and quality were the main targets, which were analyzed after harvesting. The data we got showed that 4% of bamboo biochar had good effects on both fresh weight and quality (total sugar content; dry matter) of those three crops. The fresh weight increased up to 47.2% for radish and 14.2% for carrot. The dry matter content enhanced from 4.7 to 6.9% for sweet potato; 0.8% for carrot. The total sugar content of sweet potato was enhanced significantly comparing with that of control at p level p<0.05, from 13.6 g/l of control to 18.1 g/l and 26. 7 g/l of 2% treatment and 4% treatment, respectively.
