WebThe degree of buffering is highest between the soil pH of 4 and 6 and drops off below and above this range. Importance of buffering in agriculture; The importance buffering in soils is mainly two folds: i) The stabilization of soil pH. ii) Calculations of amount of amendment necessary to affect a certain change in soil reaction. WebA greater pH buffering capacity leads to slower pH change, and pH buffering capacity can be used to predict the acidifying trend of a soil. The pH buffering capacity can also be used to estimate lime requirement when an acid soil is ameliorated (Aitken et al. 1990), with greater pH buffering capacity indicating more lime would be needed to ...
WebWhat is soil pH buffering? The buffering capacity of a soil indicates the capacity of the soil to resist pH change. Hydrogen ions in soil are present both in the soil solution and adsorbed onto the soil surfaces. pH measures the concentration of hydrogen ions in the soil solution.
