Abstract
Abstract Concentration of soil solution Al in mineral soils was related to the percent Al saturation of the effective CEC. In organic soils, however, the concentration of Al in the soil solution was more related to the amount of exchangeable Al than to percent Al saturation. Soils with increasing organic matter content had a lower content of soil solution Al at a given pH. Liming increased the growth of corn on mineral soils when the Al saturation was greater than 70%. On all soils except one, corn responded to liming when the concentration of soil solution Al was greater than 0.40 meq/liter. Soybeans responded to liming on mineral soils when the Al saturation was greater than 30%. On all soils soybeans responded to liming when the concentration of soil solution Al was greater than 0.20 meq/liter.
