Leachable cation concentrations of Moquah Barrens, Wisconsin, USA, ash samples were determined by total elemental concentrations and positively related to ash pH. Leachable element (LE) concentration of calcium, Ca (a); magnesium, Mg (b); and potassium, K (c) were all positively related to their total element (TE) concentrations in ash (all P < 0.05). Solid lines represent linear regression fit, and dashed lines show the 1:1 fit. The sum of these three TE cation concentrations (conc.) was positively related to ash pH (d)
