On the Acid−Base Properties of Humic Acid in Soil
Environmental Science & Technology, 2006Humic acid was isolated from three contrasting organic-rich soils and acid-base titrations performed over a range of ionic strengths. Results obtained were unlike most humic acid data sets; they showed a greater ionic strength dependency at low pH than at high pH.

Abstract 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.

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 ...
