초록
A pot experiment was conducted to evaluate the effect of organic matter addition to paddy soil on the solubility of arsenic (As), iron (Fe), and manganese (Mn) in soil and on As uptake by rice. Organic matter (rice straw, cattle manure, fowls manure, and swine liquid manure), except for rice hull and rice bran (the highest C:N ratio) had no effect on As release from the soil until the middle of the growth period of rice. However, As concentration in soil solution after that time was relatively high for all treatments. This result was probably attributable to the organic matter induced reductive dissolution of Fe (hydr)oxides combined with As in soil. As concentration in soil solutions from rice hull, rice bran, and cattle manure treatments was about four times higher than that of the control, since the panicle formation stage and the As concentration in brown rice from the treatments was 0.68-0.82 mg kg-1, which was about two times higher than that of the control. The As content in brown rice from swine liquid manure (the lowest C:N ratio) treatment was 0.33-0.36 mg kg-1, similar to the control. Our study indicates that some organic matter addition to paddy soil with high As concentration could cause As release from the soil and consequently elevate its concentrations in rice grain. We recommend swine liquid manure among the studied organic matter to be added to paddy soil, where As concentration is high.
Abstract
A pot experiment was conducted to evaluate the effect of organic matter addition to paddy soil on the solubility of arsenic (As), iron (Fe), and manganese (Mn) in soil and on As uptake by rice. Organic matter (rice straw, cattle manure, fowls manure, and swine liquid manure), except for rice hull and rice bran (the highest C:N ratio) had no effect on As release from the soil until the middle of the growth period of rice. However, As concentration in soil solution after that time was relatively high for all treatments. This result was probably attributable to the organic matter induced reductive dissolution of Fe (hydr)oxides combined with As in soil. As concentration in soil solutions from rice hull, rice bran, and cattle manure treatments was about four times higher than that of the control, since the panicle formation stage and the As concentration in brown rice from the treatments was 0.68-0.82 mg kg-1, which was about two times higher than that of the control.
