Abstract
This paper deals with problems of measurement and interpretation of rainfall acidity in terms of effects on the soil-plant system. The theory of the carbon dioxide-bicarbonate equilibria and its effect on rainfall acidity is given. The relationship of a cation-anion balance model of acidity in rainfall to plant nutrient uptake processes is discussed, along with its relationship to a model previously proposed in the literature. Average H(+) concentration calculated from pH measurements does not appear to be a satisfactory method of determining H(+) loading from rainfall if the rain is not consistently acid. Calculating loading from H(+) minus HCO3(-), strong acid anions minus basic cations, or net titratable acidity is suggested. The flux of H(+) ions due to plant uptake processes and sulfur and nitrogen cycling is considered. H(+) is produced by oxidation of reduced sulfur and nitrogen compounds mineralized during decomposition of organic matter. The soil acidifying potential due to the oxidation of the NH4(+) in rainfall is apparently of a similar magnitude to the direct acidity inputs.
