摘要：Wastewater irrigation of agricultural lands since couple of decades lead to elevation of heavy metal accumulation in the soil that consequently becomes a major constituents of food chain and poses severe threats to human health. Present study evaluated the role of organic additive(OAs) and inorganic additive(IAs) in ameliorating the heavy in the soil and their availability to plants. Farmyard manure and NPK fertilizer were used as organic and inorganic additives at four contaminated sites of District Sargodha respectively. Soil amendments not only led to improvements in physico-chemical properties of the soil also lowered the phyto-availability of heavy metals in treated soil. Phyto-availabilty of Cd, Pb, Zn, and Cu was significantly lowered in soil treated with farmyard manure(OAs)while, phyto-availabilty of Ni and Mn was significantly lowered in NPK treated soil (IAs)in comparison or pre-treated soil. Both organic and inorganic additives if used in combination can be more effective and economic for safe and sustainable food production to meet the current demands of growing population.
