A field experiment was designed for study of the effects of soil type on movement of zinc in the soil and of soil type and levels and placements of zinc sulfate on growth of 1‐year‐old tung trees. The soils were Savannah and Red Bay fine sandy loams, Lakeland fine sand, and Arredondo loamy fine sand. The treatments consisted of the factorial combination of three levels of zinc sulfate with three placements and a check plot (no zinc sulfate). At the end of 1 year the rate of zinc movement through the four soils was in the order Lakeland > Red Bay > Savannah > Arredondo. Very little zinc was absorbed by the tung trees from surface applications on the Arredondo soil, but the trees obtained sufficient zinc when the zinc sulfate was mixed with the soil. In contrast, zinc mobility on the Lakeland soil was so great that 1 ounce applied on the surface proved toxic. Although there was little lateral movement of zinc in the soils, the movement was primarily toward the tree rather than away from it.
