Compost can be used to remediate metal-contaminated sites because it binds metals and reduces metal uptake by plants. A greenhouse experiment was conducted to test the effectiveness of compost to remediate Zn toxicity to plants and to determine its effect on zinc (Zn) distribution among operationally defined forms. Cecil soil (Typic kanhapludults) was amended with 0 to 5000 mg kg-1 Zn and biosolid compost at 0, 100, and 300 tons ha-1, and then corn (Zea mays L.) was planted. After 42 days of growth plants were weighed and analyzed for Zn concentration. Soil was analyzed for Mehlich 1-extractable Zn and fractionated by a sequential extraction procedure for forms of Zn. Compost lowered soil pH while increasing CEC, exchangeable hydrogen and percent carbon. Concentrations of Mehlich 1-extractable Zn were decreased by compost addition. Compost additions decreased plant Zn concentration and allowed more plant survival with toxic levels of soil Zn. Compost amendment redistributed Zn from the water soluble and exchangeable fractions to the manganese oxide and amorphous iron oxide fractions, which shows a change in form of Zn from more plant available to less plant available. Biosolid compost soil amendments decrease plant availability of Zn making it less toxic to plants even where it decreases soil pH, which would tend to have the opposite effect. |
