| Abstract: | Dif fere ntly textured podzolic soil were leached with various solutions or sequences of solutions to study, the mobilities of Zn and several other heavy metals is the soil. The study helps to understand how to maintain the optimum contents of these minor elements studied. Followings are experiment results. 1.Soils leached by phosphate solution lowered the mobility of Zn,Cu, Fe, Mn and Ni;2.Soils previously leached by ZnCl2, FeCl2, or NiSO4 solutions lowered the mobilities of Zn, Fe and Ni in part of the tested soils in comparison with those soils leached with alternative sequences of solutions; 3. Soils leached with solutions in following sequences(CuCl2, EDTA, H2O, CaHPO4) promoted crop growth and lowered Cu content in barley seedling; 4. Soils leached with following sequence(CuCl2, EDTA, CaHPO4, H2O)gave poorer crop growth and higher Cu content in barley seedling; 5. Pot culture experiments of barley showed that in pot of soils leached with CuCl2 solution retarded barley growth and gave excess Cu content in seedlings; and 6.Most soils in above pots leached subsequently by EDTA, CaHPO4, H2O or other sequences of solutions gave better crop growth and lower Cu content in seedling. |
