Environmental impact of the soils of Peshawar basin, Pakistan on the agriculture and ecosystem of the region
Peshawar basin is situated at the southern foothills of the lesser Himalayas in the North West Frontier Province (NWFP) of Pakistan. It is mainly composed of the Quaternary fluvial and lacustrine sediments. The soil of the basin has been classified as Peshawar piedmont soil, Peshawar floodplain soil and Peshawar lacustrine soil. Analyses of these soils show that concentration of SiO2, TiO2, Fe2O3 and Mn() are in the range for normal soil. However, Al2O3, Ca(), MgO, Na2(), K2(), P2()3 and the heavy metals Cu, Cr, Ni, Pb and Zn, are higher than concentrations normally found in soils. Soil in certain areas of the Peshawar piedmont and the Peshawar floodplain has heavy metal concentrations that should be further investigated. The high concentrations of Ca(), NaO, K2() in these soils can be attributed to both water logging and salinity in the area while high Mg(), Cu, Ni and Cr can be correlated with the rocks of the Dargai ultramafic complex and the high P2O5 could be contributed by both alkaline rocks and fertilizers.
