Determine the importance of Calcium in soils

Calcium in soils is usually abundant except in acid soils, which occur in humid areas due to excessive leaching. Deficiency of calcium leads to increased nucleotide formation but the synthesis of nucleic acid decreases. Also calcium deficiency in soils leads to accumulation of Al3+, Mn2+ ions in plants in harmful concentrations. When compared with most potassium minerals,   calcium bearing minerals are usually much more soluble. As a consequence, there is nearly always more exchangeable calcium on the clay/humus colloid than potassium.
