Abstract
In field experiments, P‐induced Zn deficiencies were observed in field corn in 1958 and in sweet corn, tomatoes and field corn in 1959.In greenhouse experiments with Red Kidney beans (Phaseolus vulgaris), severe P‐induced Zn deficiencies occurred with P fertilization. Zinc absorption was increased by Zn fertilization and decreased by P fertilization. Phosphorus uptake was increased with P fertilization and decreased by Zn fertilization. When both Zn and P were applied, the uptake of both Zn and P were reduced.
