Sand cultures with P 32 and Zn 65 incorporated were used to determine the influence of CaCO 3 and P on uptake and translocation of Zn by navy bean plants ( Phaseolus vulgaris ). Adding CaCO 3 decreased dry weight, top‐root ratio and Zn concentration in all plant parts. Calcium carbonate decreased the translocation of Zn, and increased the translocation of P, from roots to leaves. The results suggest that excess CaCO 3 influences P‐Zn relationships within the plant as well as effecting solubilities of compounds of Zn and P. Water extractable Zn and P were determined at the end of the experiment. Adding CaCO 3 decreased the amount of water extractable Zn and P. On the other hand, high P increased the amount of water extractable Zn which is evidence that the P‐Zn interaction problem is not in the soil external to the plant.
