Growth performance of Jatropha curcas cultivated on local abandoned bauxite mine soil

Lack of regulation in bauxite mining has caused land contamination in Malaysia. Land rehabilitation requires plants with excellent adaptability to adverse conditions. Inedible, economical viable crops with environmental co-benefits, like phytoremediation, are preferred. In this study, Jatropha curca...
