The Recycling Rate and Budget of Trace Element Mn and Cu in Agroecosystem Using ICP-AES
The recycling rate and budget of Mn and Cu under different fertilization regimes by using long-term field experiment and ICP-AES analysis were investigated in the present paper. The results showed that the recycling rates of Mn and Cu were greater than 80% because of sediment recycling type, and the values increased with the amount of feed stuffs increasing. Both the two elements under different fertilization regimes showed budget deficit, with the deficit order of M<(or≤)NPK+M<CK<NPK, showing that chemical fertilizer application might induce severe deficit, while application of recycling organic matter might minimize the unbalance.
