Followings are the statements with respect to the addition of liming materials in the soils.
(A). All liming materials (oxides, hydroxides or carbonates) when applied to an acid soil react with carbon dioxide and water to yield bicarbonates.
(B). When applied to an acid soil, the hydrogen and aluminium in the liming materials replace the magnesium and calcium on the colloidal complex.
(C). Applied carbonate and bicarbonate liming materials replace hydrogen and aluminum on the colloidal complex leading to the evolution of free carbondioxide
(D). Adsorption of calcium and magensium ions raises the percentage base saturation of the colloidal complex in turn decreasing the soil pH.
