Active acidity (or soil-water pH) is due to the presence of H+ ions in the soil solution. Active acidity will indicate a need for lime. Potential acidity (or buffer pH) is the amount of Al3+ and H+ ions that are adsorbed on soil particles (negatively charged cation exchange sites) and can be desorbed from these exchange sites to the soil solution (buffering the soil) when liming materials are
