Canadian Journal of Physiology and Pharmacology, 1984
A summary of important chemical properties of soil is given and the way in which acid rain may affect these properties is discussed. Acid rain may suppress microbiological decomposition and nitrification processes, thus influencing the nutrient status of soils.

A soil is acidic if the pH value of the soil solution is less than 7.0. This condition is met in many soils where rainfall exceeds evapotranspiration, including Alfisols, Histosols, Inceptisols, Oxisols, Spodosols, and Ultisols—almost half of the ice-free land area worldwide.

Outlook on Agriculture, 1982
Although their occurrence is sporadic, the world's total area of pyritic soils is enormous. Such soils can be virtually worthless due to an accumulation of acid sulphate resulting from the oxidation of pyrite, but techniques have been developed—based particularly on careful control of the water table—to bring them into productive cultivation.

Acidic sulfate soils are formed from potential acidic sulfate soils that are characterized by the accumulation of pyrite (FeS2). Upon drainage of these soils, the pyrite oxidizes to produce sulfuric acid and hence acidic sulfate soils. The acid formed commonly decreases the soil’s pH to less than 4, and sometimes the pH becomes as acid as 2.

Soil Biology: Soil Animals and Soil Acidity
1994The role of soil animals is in general poorly known. Several studies have shown that soil fauna may accelerate the decomposition rate and contribute to the release of plant nutrients, but there is a need for more exact quantitative knowledge in this field (e.g., Anderson et al.

Soil Biology: Soil Microflora and Soil Acidity
1994The low content of inorganic nutrients in forest soils makes the microbial activities in this ecosystem an important factor in regulating the amounts of available nutrients for the growth of trees. In such soils most of the fine roots of forest trees will be in an intimate symbiotic association with the mycelia of different fungi, thus greatly ...
