Availability of cobalt-60 to corn and bean seedlings as influenced by soil type, lime, and DTPA
Uptake of /sup 60/Co by corn (zea mays) and bush beans (Phaseolus vulgaris) seedlings was affected by plant species, soil type, and soil amendment. Bean leaves preferentially accumulated /sup 60/Co in comparison with corn leaves. Both the DTPA and (lime and DTPA) treatments enhanced /sup 60/Co uptake by both plant species, notably in the Troup soil which had lower cation exchange capacity (CEC) and lower soil fertility in comparison with Dothan soil. Conversely, soils with lime but without the chelating agent suppressed /sup 60/Co uptake. This dictates that farming practices should be closely evaluated if crops for livestock and human consumption are to be raised in fields contaminated by radionuclides.
