摘要：Soil Cd pollution resulting from human activities has become a serious food safety concern. This study was to investigate the impacts of three soil amendments including a humic acid material, pig manure and peat combined materials and biological material on soil Cd availability. Different factors are studied. Results showed that soil Cd conversion rate under three amendments significantly increased after 20 d treatment. This research demonstrated that biological material could be an effective soil amendment to reduce the Cd health and ecological risk in the Cd-contaminated soil.
