If, for example, your soil sample has 50% sand, 20% silt and 30% clay, it would be described as a ‘sandy clay loam’. If it was 70% clay, 20% silt and 10% sand it would be described as a ‘clay’. WebA soil is acid when hydrogen ions predominate in the soil. The degree of acidity is expressed in terms of pH, which is defined as the negative logarithm of the hydrogen ion activity. Therefore, the pH of a 0.01-molar hydrogen ion solution is. pH = −log ( 10−2 mol H+ L) = 2 pH = − log ( 10 − 2 mol H + L) = 2.
