Uptake of Co by corn (Zea mays) and bush beans (Phaseolus vulgaris) seedlings was affected by plant species, soil type and soil amendment. Bean leaves preferentially accumulated60Co in comparison with corn leaves. Both the DTPA and (lime and DTPA) treatments enhanced60Co 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 suppressed60Co 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.
