Summary
The application of FeEDDHA to a calcareous soil significantly increased yield and alleviated severe lime-chlorosis in a genotype ofEucalyptus obliqua that is native to acidic soils. The alleviation of chlorosis brought about a significant decrease in the levels of P, Ca and K but an increase in the uptake of Fe in leaves. The total Fe content of foliage, however, was poorly coorelated with the occurrence of lime-chlorosis.
It was concluded that the differential susceptibility ofE. obliqua to lime-chlorosis is related to interactions between Fe and Ca, as well as Fe and P, occurring during the absorption and translocation processes.
