Leachability of nitrogen forms, cations, and metals was evaluated in an entisol amended with compost. In this study, sugarcane filter cake (SF) and municipal solid waste plus biosolids (MSW + BSD) compost were applied to a Candler fine sand (hyperthermic, uncoated Typic Quartapsamments) at rates equivalent to 200 kg N ha-1(on air-dry weight basis) and intermittently leached with deionized water in 220 mL fractions for a total of 1,760 mL. The concentrations of NO3-N in leachate were below 10 mg L-1 (maximum contaminant limit of NO3-N; drinking water quality standards) for both compost sources. Leaching of most elements was greater from the soil amended with SF as compared to that with MSW + BSD. The highest concentrations of most elements (except P, Fe and Al) were observed in the second or third leachate fractions. The cumulative amount of NO3-N recovered in 1760 mL leachate accounted for 2.9 and 2.7% of total N applied using SF and MSW + BSD, respectively.
