The effects of source and placement of zinc and phosphorus were studied in several greenhouse experiments. A Zn and P deficient soil was utilized and sweet corn was grown as the test plant. When Zn fertilizer materials were mixed well with the soil ZnSO 4 and organic sources such as ZnEDTA and Rayplex‐Zn were equivalent in their effectiveness for the correction of Zn deficiency. However, if the fertilizer was banded under the seed, ZnEDTA was more effective than the inorganic sources. A small amount of mixing appeared to improve the effectiveness of Zn, or P, or both fertilizers markedly. Granulation greatly reduced the effectiveness of ZnSO 4 , ZnNH 4 PO 4 , and Rayplex‐Zn.
