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. Web13 apr. 2024 · Another factor driving differences among site-level responses to drying in tropical forests could be soil texture. Among tropical soils with clay contents from ∼18% to 80% clay, the soil moisture levels for max CO 2 flux were positively correlated to clay content (Meir et al., 2015).
