Abstract: A field positioning experiment was conducted to examine the distribution of organic carbon and easily oxidized organic carbon, and their correlation with the concentrations of heavy metals in soil profile after four years continuous application of three different kinds of organic fertilizers. The results showed that after applying organic fertilizers, organic carbon and easily oxidized carbon mainly accumulated in the 0-15 cm soil layer, and their concentrations decreased with increasing soil depth. When high amount of chicken manure was applied, organic carbon could migrate to the 15-30 cm soil layer, and easily oxidized organic carbon could migrate to the 60-90 cm soil layer. Organic carbon didn’t significantly migrate when pig manure and sludge were applied, while easily oxidized organic carbon migrated to the 60-90 cm soil layer under high amount application of pig manure and sludge. The proportion of oxidized organic carbon to total organic carbon was much higher in the treatments of pig and sludge manure application as compared to chicken manure. There was a significant positive correlation between the distribution of organic carbon and easily oxidized organic carbon and Cu, Zn and Cd in the soil profile after application of different organic fertilizers.
