Abstract:
The particular study aims to assess the soil and irrigation water quality in
agricultural fields near the vicinity of Khanpur Dam. The (irrigation water, soil)
samples were collected from the selected area of sampling according to standard
protocols and then digested, using the standard laboratory protocols. Trace elements
in both the soil as well as the irrigation water were analyzed through atomic
absorption spectrometer. The subjected heavy metals result was as follows; The Lead
ranged from 0.03 to 3.16 mg/L in irrigation water and 18.23 to 63.58 in soil samples.
The Chromium concentration varies from 0.02 to 1.9mg/L in water and 25.3 to
67.3mg/Kg in soil whereas, the concentration of Cadmium ranged from 0.001 to 1.6
mg/L in water and 0.08 to 3.11 mg/Kg in soil .The Zinc metal concentration ranged in
water from 0.01 to 0.09mg/L and in soil its ranges from 0.16 to 1.92mg/Kg while in
water the Nickel ranged in between 0.01 to 1.17mg/L and 20.42 to 43.3 mg/Kg in soil.
The Copper ranges from 0.01 to 1.41mg/L in irrigation water and 11.31 to 35.07
mg/Kg in soil .The last metal subjected was Arsenic and its concentration in water
ranged from 0.1mg/L to BDL whereas, in soil it was 0.0075-0.16 mg/Kg. Analysis of
physicochemical parameters for soil and irrigation water was done. Furthermore, the
bar graphs were used to describe graphical representation. The trace elements in
(irrigation water) were found in decreasing order of (Cr>Cu> Ni>Cd>Pb>Zn>As) and
(Cd>Ni>Pb>Cr >Cu >Zn >As) in soils. Whereas, (Cu, Cr, Cd, As and Ni) were
detected in IW above the prescribed limits whereas, (Cd) in soil was present in huge
concentration beyond the standards limits. This research concludes the high
concentration of trace elements majorly in irrigation water and soil irrigated using this
water was also found highly metal contaminated. However, in physicochemical
parameters the sodium adsorption ratio of irrigation water was much high and
macronutrients in soil were present in abundance.
