The district of Dharmasraya, Sijunjung and Pasaman Barat are the three main locations of illegal gold mining in West Sumatra. This kind of activity triggers a lot of land-use changes and the loss of agricultural land within those areas and creates environmental problems as well. Decreasing agricultural land will bring a significant impact on food availability within the region. To protect the scarcity of food, we conducted remediation of ex-gold mining land on those three locations by using biochar made from rice husk. This study was carried on at Batu Manjulur village, Kupitan sub-district in Sijunjung for four months, where soil sample was analyzed at Soil Science Department, Faculty of Agriculture, Andalas University. The experiment use 6 level of biochar application, run from A [without biochar]; B [fulfil of 2% soil organic matter content [SOM]]; C [fulfil 3% SOM]; D [fulfil 4% SOM], E [fulfil 5% SOM] and F [fulfil 6% SOM] with three replication. The result shows the application of rice husk-derived biochar increased soil quality including the chemical properties of the soil and improving nutrient retention and land productivity.
