Abstract

A simple model for soil acidification describes the observed pH and base saturation profiles in a Swedish podzol affected by acid deposition. The model is based on a mechanistic respresentation of ion exchange and the weathering rate and is based on a mass balance for calcium and alkalinity. The model has been extended to include a dynamic model for dissolution of limestone in soils. This model has a potential use as a tool for planning and evaluation of different terrestial liming operations.
