Synopsis Differences in soil fertility influenced the amounts of N, P, and K taken up by corn plants, but did not markedly change the seasonal pattern of uptake and distribution of these elements in the plants. Large proportions of the N and P and a small proportion of the K were translocated from other plant parts to the grain. Late in the season K was lost from the leaves to the stalks.
