- •
Both chemical and hydrological factors contributed to inorganic soil acidification.
- •
Acidification occurred on oxidation of sulfide minerals on re-wetting after drought.
- •
Early amphibian breeders had to cope with acidification in some sites.
- •
Water-table declining levels can decrease the hydroperiod length of breeding sites.
- •
Loss of Mg2 + might be an early warning of an eventual water-table decalcification.
- •
The S/Ca + Mg ratio of the dry sediment was a good predictor of the pH after rainfall.
