  • Title: [Effect of pig manure and rice straw on biological activity of Cd-contaminated soil].
    Author: Zhang Y, Shen Q, Xie X, Sun Z.
    Journal: Ying Yong Sheng Tai Xue Bao; 2003 Nov; 14(11):1997-2000. PubMed ID: 14997665.
    Abstract:
    Studies on the effects of pig manure and rice straw on the biological activity of Cd-contaminated permeable paddy soil showed that Cd-contaminated soil had a declined biological activity. After applying organic manure, the content of soil available Cd decreased significantly, being about 40%, and soil microbial C, N and P and soil dehydrogenase and catalase activities increased 30%-100%. There existed a negative correlation between soil available Cd and soil microbial C and N, indicating that microbial C and N could be used as an index of Cd-contaminated soil.
