Abstract
Equilibrium studies on soil require reliable estimates of ion concentrations in the soil solution underfield conditions. We evaluated the previously described iterative method to approximate the equilibriumsoil solution (ESS) with four acid forest soils. We examined for which ions the ESS is suitable, makinguse of the fact that concentrations in water extracts are functions of the soi1:solution ratio. The electricconductivity, pH, and the concentrations of base cations, Mn2+, NO-3, S042+, and dissolved organiccarbon (DOC) were usually linear with the soi1:solution ratio in water extracts, whereas no relation wasobserved for A1 (with one exception) and Fe. Assuming that the ESS can be attributed the soi1:solutionratio of the field moist soil at the time of sampling, concentrations appeared as the continuation of thelinear relation with the soi1:solution ratio for base cations, pH, and the electric conductivity. Thisindicates that the ESS actually represents field conditions for these solution properties. For A1 waterextracts allowed no evaluation of the ESS result. The ESS underestimated SO4" concentrations underfield conditions, presumably because the lack of DOC in the solutions added distorts the balanceamongst anions.
