WebIn order to provide adequate amounts of the base cations, proper management of pH is crucial. If soil pH is low, additions of lime and/or organic matter may increase the CEC for soils high in low activity clays. Low activity clays have a low shrink and swell potential. With additions of nutrients, these soils may be very productive soils. Table 5. WebThe pH of a soil is a measure of the hydrogen ion concentration in the soil solution. pH is a the negative logarithm of H+ concentration in moles / liter: pH = - log [H+] and is therefore a solution measurement which only reflects the presence of acid cations adsorbed on soil colloids. A pH scale is shown below along with some reference points.
