Abstract
Present study entitled, “Quality appraisal of underground
waters of Gharaunda and Indri blocks of Karnal district, Haryana” and to
assess the effect of different quality waters on physico-chemical properties
of soils in respective blocks, was under taken. Underground water
collected from three hundred fifty three and four hundred fifty four tubewells
water samples from fifty eight villages of Gharaunda and eight five
villages of Indri block respectively were collected randomly during
November, 2004-2005. On the basis of water analysis, soil samples from 4
depths (i.e. 0-15, 15-30, 30-60 and 60-90 cm) per site from 6 sites of
Gharaunda and 6 sites of Indri block were collected and analysed for their
physical and chemical properties.
pH, EC, SAR and RSC of the irrigation waters of Gharaunda
varied from 7.45-8.98, 0.5-3.2 dSm-1, 0.62-8.86 (m mole l-1)½ and nil -6.5
me l-1, with mean values of 8.29, 1.1, 3.22 and 1.18, respectively.
Likewise pH, EC, SAR and RSC values varied from 7.24-8.93, 0.35-2.9
dSm-1, 0.46-8.96 (m mole l-1)½ and nil-7.7 me l-1, with mean values of
7.97, 0.99, 2.69 and 1.02 respectively, in Indri block. Dominant cation in
irrigation water was sodium followed by magnesium and calcium, in case
of anions, bicarbonate was the dominant ion followed by chloride and
sulphate. Fluoride ranges from 0.01-2.1 ppm and 0.001-1.17 ppm in
Gharaunda and Indri block, respectively. In both Gharaunda and Indri
blocks, maximum number of underground water samples had EC between
0.5 and 1 dS m-1 and with increase in EC, number of tube-well water

samples decreased, under various range. As per Manchanda (1976)
classification 85.84, 0.85 and 13.31 per cent waters of Gharaunda
block were classified under good, marginal and sodic, respectively. In
Indri block 89.43 and 10.57 per cent under ground waters were found
good and sodic, respectively. As per AICRP (1989) classification, 85.27,
5.38, 8.78 and 0.57 per cent waters of Gharaunda block were classified
under good, marginal saline, marginal alkali and alkali, respectively.
Whereas in Indri block 87.44, 1.54, 9.69 1.33 per cent of respective
underground water were found in good, marginal saline, marginal alkali
and alkali category in Indri block. Effect of irrigation water on salt
build up of soil was highest in the surface layer, which decreased with
increase in stage of depth. A linear relation was obtained between EC of
irrigation water (ECiw) and EC of soil (ECe).
