Effect of the Separation of Nitrogen and Sulfur Sources on Sulfur Uptake by Corn¹

ABSTRACT

The effect of fertilizer N and S sources on the absorption of S by corn (Zea mays L.) was studied in the greenhouse with the use of ³⁵S. When the N and S sources were separated by a physical barrier, the NH₄ ion, when compared to the NO₃ ion, produced a significant increase in the S absorption from the fertilizer. The data indicate that the influence of the N source on S absorption is the result of physiological reactions or processes within the plant or the root tissue. The separation of the N and S sources had no significant effect on the total S and total N content of the tissue.
