Abstract |
The paper summarizes the occurrence and distribution of soluble organic acids in soils and reviews the role of organic acids in mineral weathering. Organic acids, particularly humic and fulvic acids, are present in soil solutions and these acids have a major influence on the translocation of iron and aluminum in soil profiles. Organic acids may also accelerate the weathering of primary silicate minerals. The paper deals with the controversy as to whether or not organic acids at natural concentrations significantly accelerate the rate of dissolution of primary silicate minerals. |
