Abstract

The present paper deals with the physico-chemical properties of calcium and magnesium in sewage and tubewell irrigated fields of district Aligarh, Uttar Pradesh. Calcium ranged from 90-184 mg/100 g (115±22 mg/100 g) in sewage irrigated and 82-180 mg/100gm (116±31 mg/100gm) in tubewell irrigated fields. Magnesium ranged from 9.7-36.4 mg/100 g (20.45±5.56 mg/100g) in sewage irrigated and 13.3-44.0 mg/100 g (21.53±7.92 mg/100gm) in tubewell irrigated fields. Higher concentration of magnesium in tubewell irrigated than sewage irrigated fields might be due to hardness of tubewell water.
