Webion if the soil pH is less than ~6.2 and two H+ ions is the soil pH is above 8.2. Monoammonium phosphate (MAP), single superphosphate (SSP) and triple superphosphate (TSP) all add P to soil in the form of the H 2 PO 4-ion, which can acidify soil with a pH greater than 7.2 but has no effect on soil pH in acidic soils. The form of P in diammonium WebSoils become extremely acidic (pH < 4) when large amounts of reduced forms of S are oxidized to H2SO4 if the soils are exposed to oxygen when they are drained or excavated. With a ≥0.15-m-thick sulfuric horizon that is often present, such soils are commonly referred to as acid sulfate soils.
