Although extensive use of agrochemicals is prevalent in Punjab posing severe risk of heavy metal contamination of soil, but the levels of heavy metals in studied soils were below the various maximum permissible limits (Table 3).
This might b due to leaching of metals to lower soil layers, due to sandy texture of soil and precipitation during kharif season.
The soil heavy metal contents observed in the present study were in similar levels to the heavy metals observed in agricultural soils of other parts of Punjab (Dheri et al., 2007; Kaur et al., 2014).
