Abstract: In order to assess the groundwater quality and its effect on soils of right bank canal command area of Pench irrigation project in Nagpur district particularly in Parsheoni Tahasil, the present study was undertaken. Soils of this area are clay loam to clayey with more than 35 per cent clay. Bulk density of these soils varied from 1.28 to 1.53 Mg m-3. The saturated hydraulic conductivity (HC) of these soils ranged from 0.81 to 2.71 cm hr-1. Soil reaction was low to moderately alkaline (pH 7.43 to 8.53). These soils are non-saline as indicated by the electrical conductivity, which ranged from 0.119 to 0.552 dS m-1 at 25 oC, but more accumulation of salts was observed in surface layer of these soils. Organic carbon content (2.7 to 6.2 g kg-1) was low to moderate. The calcium carbonate content of these soils ranged from 1.5 to 6.13 per cent. The high CEC (33.76 to 58.49 cmol (p+) kg-1) and base saturation (90.5 to 95.1 per cent) indicate the potential of these soils in terms of fertility. The exchangeable cations were in order of Ca > Mg > Na > K. The Ca/Mg ratio of soil varied from 1.80 to 2.9 and the exchangeable sodium percentage (ESP) varied from 2.67 to 4.86 whereas the exchangeable magnesium percentage (EMP) ranged from 23.09 to 30.62 and exchangeable calcium percentages ranged from 55.22 to 66.16. These soils of study area were not qualified for alkali soils as the ESP was less than 15 and so soils are very good for cultivation point of view. In the saturation extract, soluble sodium percentages which ranged between 23.49 to 60.64. The SAR ranged between 0.9 to 3.07. The soluble Ca/Mg ratio ranged between 1.2 to 2.93. The water samples of this area had medium salinity and low sodicity hazards (C2S1). On the basis of above facts, it is concluded that, in order to optimized the production on sustainable basis, injudicious and over irrigation to crops should be avoided and seepage losses through irrigation canals should be controlled.
