Abstract: A Long term fertilizer experiment was conducted at Sagadividi Farm, College of Agriculture, Junagadh Agricultural University, Junagadh to using Groundnut as test crop studing the status of available heavy metals (Fe, Mn, Zn, Cu, Pb, Cd, Cr and Ni) in soil (0-15 cm) after 32nd, 36th and 40th years. All the heavy metals slightly increased with increase in levels of N fertilizer. The significantly highest Ni, Fe and Zn content in soil during 32nd years, Cr, Cd and Fe during 36th years and Zn, Cd and Cr during 40th years were observed with the application of 25 kg N ha-1 in the form of urea over control. The DTPA extractable Fe, Mn, Zn, Cu, Pb, Cd, Cr and Ni contents in soil were significantly higher with application of 100 kg P2O5 ha-1 through single super phosphate over control after 32nd, 36th and 40th years. The DTPA extractable Fe, Mn, Zn, Cu, Pb, Cd, Cr and Ni contents slightly increased with increase in levels of P2O5 fertilizer. The accumulation of Cu, Mn, Zn, Fe, Cd, Cr, Ni and Pb in soil was 1.41, 8.00, 1.12, 8.93, 0.07, 0.15, 0.36 and 0.99 mg kg-1 from their initial values of 0.96, 4.00, 0.20, 1.73, 0.02, 0.03, 0.06 and 0.33 mg kg-1, respectively with fertilizer application after 40th years. These data clearly indicated that the accumulation of heavy metals in the soil was increased considerably with increase in the application of nitrogen and phosphatic fertilizer after 40th years over their initial value of soil.
