Abstract

Abstract: A field experiment was conducted using Brassica campestris ssp.pekinensis to assess effect of fertilization on migration and accumulation of Cr,Cu and Ni in the soil-brassica cropping system.Heavy metal absorption capacity of brassica varied with the fertilization treatment showing a decreasing order of organic fertilizer>compound fertilizer>urea.Acumulation of Cu,Cr did with the part of the plant,displaying an order of root>roof>stem.Migration of these heavy metals from soil to brassica demonstrated an order of Cu>Ni > Cr,and effect of fertilization reducing content of available heavy metals in the soil did with the fertilization treatment,revealing an order of organic fertilizer>compound fertilizer>urea.

Key words: heavy metal, soil, fertilizer, electroplating wastewater, Brassica campestris ssp.pekinensis
