| Abstract: | The availability of various Cu fractions in plant-soil system and its inducing effect were studied by partial dissolution procedure and stimulated Cu forms. The results showed that the sequence of availability of Cu forms to plant is soluble plus exchangeable Cu and organic matter bound Cu > Cu bound to carbonate > Fe/Mn oxide bound Cu > residual Cu. Effects of EDTA on dissolution of Cu from soil and absorb by and transfer within plant were greater than those of monosodium glutamate waste water and citric acid waste water. |
