1. Actual Acid Sulfate Soil (AASS) likelihood is indicated by Low (L & no shade)(pHF > 5), Medium (M & yellow shade)(pHF 5 ≤ pHF < 4) and High (H & red shade)(pHF ≤ 4).
2. Potential Acid Sulfate Soil (PASS) likelihood is indicated by Low (L & no shade)(∆ pH from pHF to pHFOX is < 2 pH units), Medium (M & yellow shade)(∆ pH from pHF to pHFOX is ≥ 2 pH units OR pHFOX is <3)) and High (H & red shade)(∆ pH from pHF to pHFOX is ≥ 2 pH units AND pHFOX is <3)
3. Reaction L = Low strength, M = Medium strength, H = High strength, X = Extreme strength.
4. The letter in the remark column indicates the presence of the following. O - Organic; S - Shells;iron- Iron/Iron Oxide; P - Pyrite; and C - Coral.
5. Shaded TAA & SCR results are those exceeding the QASSIT action levels of 18 mol H+/t or 0.03 %S.
6. Acid-Base Account = Total Acidity (i.e.. Potential + Actual + Retained) - Total ANC
7. Shaded Net Acidity (sulfur units) %S and Net Acidity (acidity units) /t results are those exceeding the QASSIT action levels of 0.03 %S or 18 mol H+/t
8. Required Lime Rate is calculated from the net Acid-Base Account with a factor of safety = 1.5 and bulk density of 1.8 t/m³
