In the present study the effect of sewage water and canal water irrigation were compared by
their physicochemical properties and heavy metals concentration in soil. The mean values of
different physico-chemical parameters and heavy metals were : Bulk density (gm/cm3) 1.26,
Water holding capacity(%)-53.60, Temperature(ºC)-16.33, Electrical conductivity (dsm-1)-
0.122, pH-7.5, Organic carbon (%)-1.95, Available phosphorous(mg/kg)-108.44, Available
potassium (mg/kg)-121.66, Nitrogen(%)-2.22, Available Calcium (%)-2.18, Available
Magnesium (%)-0.09 and heavy metal concentration in soil were Pb-52.72, Cu-49.03, Zn-264.09
and Cd-24.66 in sewage water irrigated soil. The observed concentration of Pb, Cu, Zn was
below the Indian standards except Cd. The Enrichment factors calculated for sewage water
irrigated soil in Pb (3.79), Zn (4.12), Cu (3.12) and Cd (2.21) were moderate enrichment while
pollution index values in the samples were calculated to be lower than permissible pollution limit
of 1.0.
