We investigated the influence of amendment of charcoals derived from rice residues at 250, 450 and 850 °C on the sorption and desorption behaviors of carbofuran in a soil using a batch equilibrium method. The crop residues derived charcoals at 850 °C had higher sorption capacity than those prepared at 250 and 450 °C. Amendment of the charcoal material (<1%) prepared at 250 °C had no obvious effects on pesticide sorption in soils. The soils amended with the charcoal materials had higher sorption capacity than the original soil, and the nonlinearity of sorption of carbofuran on the amended soils increased with the content of charcoal, especially for those amended with the charcoal obtained at 850 °C. Sorption-desorption hysteresis occurred for all treatments including the control.
