Leaves from corn plants exhibiting symptoms of potassium deficiency contain considerable concentrations of molybdenum. Applications of potassium fertilizer corrected the deficiency, and a significant reduction in the molybdenum content of the leaves occurred. This inverse relation between potassium and molybdenum has not been reported previously.
