Summary
Maize seedlings with roots exposed to solutions of Al complexed by citrate, EDTA, or soil organic matter extract, were not significantly different in appearance, yields, or chemical analyses of their tops from plants not receiving Al. In contrast were plants treated with ionic hydroxy Al in the same concentrations. Roots were severely injured and their yields and Ca and Mn contents depressed; yields and P, Ca, and Mn contents of tops also were lowered. Translocation of Al to tops was negligible with chelation.
