Introduction
The agricultural, engineering and environmental problems associated with improper uses of acid sulfate soils have been well recognised (Dent 1986; White et al. 1997). Acid sulfate soils contain metal sulfides (mainly pyrite), which are subject to acid generation when they oxidise. Extremely acidic conditions with pH
Liming is a frequently used practice for treating acid in soils. Lime has a very strong acid neutralising capacity, which can effectively remove existing acid. However, where potential acid sulfate soils (not yet acidified soils containing sulfides) need to be treated to prevent future acidic problems, lime could be ineffective due to ...
