Lime-induced chlorosis in plants is characterized by some phenomena which fit into a simple hypothesis that internal pH balance is upset due to shifts in cation-anion balances. These pH changes result in precipitation of Fe in plants and fit our previous hypothesis of competitive chelation as an explanation of the multiple causes of lime-induced chlorosis. The oft-times higher concentrations of Fe in chlorotic leaves compared with green leaves can be explained, at least in part, by the tendency of Fe-deficient plants to take up Fe at a more rapid rate when it becomes available than do Fe-sufficient plants. This is a result of cation-anion balance. Part of the Fe-efficient nature of the Hawkeye soybean (Glycine max L.) may be explained by its ability to take up Cl/sup -/ which improves the internal cation-anion balance. Hawkeye soybeans, when Fe-deficient, assimilated much more /sup 14/C from bicarbonate than did Fe-deficient PI54619-5-1 soybeans.
