Cadmium has been identified as a major toxic heavy metal contaminating in our food supply chain. This study want to purpose socio-economic and appropriate technology for ameliorate cadmium contamination in soil by propose broiler litter biochar derived from incinerate pelleted broiler litter in 2 reactor that 1st in lab-scale pyrolysis reactor (PBLBL) and 2nd in 200 liter oil drum (PBLBO) at highest temperature of 500ºC. Biochar was subsequently mixed into soil with 4 mixing rate 5.00, 10.0, 15.0 and 20.0 t ha-1. Each mixing rate was added with ...
