Abstract:
Background and Objective: Dumpsites soils are known to contain high concentrations of heavy metals that could move through the food chain from consumption of vegetables and crops harvested from this site hence a study was conducted to determine the effect of poultry manure on fractions of some heavy metals (Fe, Mn, Cu, Pb, Zn, Cd, Cr and Ni) in six dumpsite soils. Materials and Methods: Soil: Manure mixture at 10:1 was incubated for 4 weeks in the laboratory. Soil pH, electrical conductivity (EC), organic manure (OM). Exchangeable Fe, Mn, Cu, Pb, Zn, Cd, Cr and Ni were extracted with 0.1 M CaCl2, Fe-Mn oxide bound Fe, Mn, Cu, Pb, Zn, Cd, Cr and Ni were extracted with 1 M NH4NO3, carbonate bound Fe, Mn, Cu, Pb, Zn, Cd, Cr and Ni were extracted with 0.05 M EDTA solution and available Fe, Mn, Cu, Pb, Zn, Cd, Cr and Ni were extracted with distilled water, respectively. The soil suspension was centrifuged and Fe, Mn, Cu, Pb, Zn, Cd, Cr and Ni in the filtrate were determined with atomic absorption spectrophotometer. Results: Application of poultry manure increased pH by 1%, EC by more than 900% and OM. The order of abundance of the fractions was carbonate bound >Fe-Mn oxides bound >exchangeable >available. Application of organic manure resulted in reduction in the available Zn, carbonate bound Cu, Zn, Ni, Cr, exchangeable Zn, Fe and oxide-bound Zn, Pb, Cd. Conclusion: Application of amendment could mitigate the threat of food chain contamination by decreasing metal concentration in the soil.
