Explanation:

The exchangeable calcium in soils ranged from 0.54 to 0.98 [cmol (p+) kg-1] with an average of 0.51 [cmol (p+) kg-1]. Out of all soil samples collected, 100 per cent samples are deficient in calcium. This might be due to loss of calcium from exchangeable 38 site during laterization. The highest exchangeable calcium was 0.98 [cmol (p+) kg-1] in (17056.291’N-73040.481’E) and lowest was 0.54 [cmol (p+) kg-1] (17056.257’N-73040.462’E). The deficiency of calcium might due to high percolating nature and intensive leaching of bases due to high rainfall. The similar results were also reported by Mohapatra and Kibe (1973) in lateritic soil of Maharashtra.
