Abstract
In this investigation, weathering rates were calculated for three eastern North American forest soils using five separate estimation techniques. In addition, leaching experiments were performed to examine the influence of selected environmental variables on the weathering process. Weathering rates varied five-fold between soils, ranging from approximately 0.5 Keq ha–1 yr–1 in a sandy Adams Spodosol, to 1.2 Keq ha yr–1 in a sandy loam Becket Spodosol, to 2.7 Keq ha–1 yr–1 in a silty Unadilla Inceptisol. Inter-soil differences in weathering rate were inversely correlated with mean soil particle size and positively correlated with total exchangeable bases in the soil profile. Study results also demonstrated major differences in weathering rates between soil horizons.
