Summary:A field experiment was conducted to investigate the effect of chicken manure compost on the fractionation of cadmium (Cd), soil biological properties and Cd uptake by wheat in a soil affected by mining activities in Hubei province, China. Compost was applied at five levels (0, 27, 54, 108, 216 t ha-1), and winter wheat (Triticum aestivum L.) was chosen as an indicator plant. Results showed that the application of compost increased soil pH and the content of total phosphorus and organic matter. Soil biological properties such as microbial biomass carbon, invertase, protease, urease and catalase activities were significantly enhanced by 0.24-3.47 times after compost application. Sequential extraction indicated that compost amendments decreased the acid-extractable Cd by 8.2-37.6 %, while increased the reducible and oxidisable Cd by 9.2-39.5 and 8.2-60.4 %, respectively. The addition of 27-54 t ha-1 compost reduced Cd content in wheat stems and seeds by 69.6-75.0 % and 10.3-18.4 %, respectively. However, only 25.5-26.5 % reductions in Cd content in wheat stems were observed in 108-216 t ha-1 compost amendments, and no significant decrease was detected for seeds. This study suggests that although compost is a suitable organic amendment to improve soil fertility and biological activities, the addition of compost should be moderated by an appropriate rate to optimize the use of compost for the reclamation of metal-contaminated soils at field scale.
