Five effects of soil acidity
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. WebNov 9, 2015 · Soils are acid because of hydrogen ions dissolved in soil solution (water in the soil) and held on the clay and humus particles. pH is a measure of the degree of acidity or alkalinity. A value below 7.0 is acid, 7.0 is neutral and above 7.0 is alkaline. As the soil pH decreases below 7.0, soils become more and more acidic.
