Abstract:
A systematic study concerning the effects of persistent fertilization and plastic sheet-covered culture on forms of Zn, Cu and Mn in a brown soil of Shenyang was conducted. The results showned that the consumptions of various forms of Zn, Cu and Mn increased after plastic sheet-covered culture. The forms of these three elements varied greatly in different fertilization treatments. The major forms absorbed by corn from soil were ogranic Zn and Cu, oxide bound Cu, exchangeable Mn and carbonate bound Mn.
