In a lysimeter experiment on alluvial loamy soil, the effect of an increasing level of urea with the addition of ZnSO4 or FeSO4 or both were tested on the yield and mineral composition of Zea mays plants. A response was found only to N application and it was of a diminishing return nature. The effect of the increasing N level in plants was reflected mostly in leaf composition and least in grain composition
