Drainage and Nutrient Effects in a Field Lysimeter Study: II. Mineral Uptake by Corn1

The mineral uptake by corn (Zea mays L.) was studied in field lysimeters for the following variables: constant water table (WT) depths, intermittent flooding, and two levels each of N and the micronutrients Zn and Cu. The WT depths. of 15 and 30 cm and intermittent flooding during early growth decreased the ear leaf concentrations of N, P, K, Zn, Cu, and B and increased the leaf concentrations of Al, Fe, Mn, and Mo. Applications of N, Zn, and Cu increased the concentrations of N, P, Zn, Cu, B, Mn, and Fe but decreased that of K. Mineral uptake under wet soil conditions was associated with reducing conditions, inhibited soil mineralization and an increase in soil pH.
