Abstract
Knowledge of the capacity and intensity of soil acidity and pH buffering processes is necessary to understand the response of a soil to liming, acid-forming N fertilizers, acid mine wastes, and acid rain. Soil pH is commonly determined after equilibrating soil with distilled or deionized water or a salt solution, as in the definition in the Glossary of Soil Science Terms. The Glossary of Soil Science Terms defines three measures of the quantity of soil acidity: total acidity; residual acidity; and salt-replaceable acidity. The chapter uses the numerical model of Bloom and Grigal to illustrate how concepts of soil acidity and pH buffering can be used to develop a rather simple model for the response of soils to long-term acid deposition. It also discusses some of the problems in modeling soil responses to long-term inputs.
