Acid Sulfate Soils
The EAL is involved in acid sulfate soil research and method development for the identification and management of these soils. EAL routinely performs screening, risk assessment and validation techniques.
There are two main analysis packages available:
- the CRS suite, and
- the SPOCAS suite of techniques.
The EAL recommends the CRS suite for the preferred techniques. Unlike the SPOCAS suite, the CRS suite of methods is not affected by significant interferences from sulfur in organic matter or sulfate minerals.
EAL also routinely conducts pH screening and acid volatile sulfur (AVS) testing. The AVS technique adopted by the EAL has been developed by leading researchers at Southern Cross University.
Collection Procedure for Acid Sulfate Soil Samples
- Acid sulfate soils should be stored/delivered cold (in an esky with ice) until delivery is possible. Notification of arrival of samples is required. EAL prefers one tightly packed 70mL vial of soil (Vials available on request, free of charge). Alternatively, 200g of soil (approx. 1 large handful) sealed in a plastic bag is sufficient. If acid volatile sulfur (AVS) is required then an additional vial is recommended and both vials should be frozen immediately.
