Iron-inefficient soybeans (Glycine max L. cultivar PI54619-5-1) were grown in a glasshouse in calcareous Hacienda loam soil with S and H/sub 2/SO/sub 4/ sufficient to neutralize the CaCO/sub 3/ and mixed throughout the soil. They were also applied in the lower one-half of the soil in the pots. The H/sub 2/SO/sub 4/ regardless of how it was placed increased Fe uptake, but the S was much less effective. Both S and H/sub 2/SO/sub 4/ increased Mn uptake, but the S did not increase Al uptake while the H/sub 2/SO/sub 4/ increased it considerably. Sulfur and a commercial form of Fe oxide were mixed singly and together in a band in the middle of pots of soil in which were grown Fe-inefficient rice (Oryza sativa L. cultivar Norin 8), corn (Zea mays L. Ys/sub 1//Ys/sub 1/ inbred), soybeans, and sorghum (Sorghum bicolor L. cultivar Combine Kafir 60). Each of the five species responded differently. Rice responded only slightly to the Fe/sub 2/O/sub 3/ and considerably to the S. Corn responded somewhat to the Fe/sub 2/O/sub 3/, but was injured by Zn toxicity with the S application which seemed not to increase Fe uptake. Soybeans responded to combined Fe/sub 2/O/sub 3/ and S and not at all to S alone, but slightly to Fe/sub 2/O/sub 3/ alone. The sorghum was not Fe-deficient in the noncalcareous soil in which it was grown. The Fe/sub 2/O/sub 3/ increased its Fe uptake, however, but S did not. The results indicate that responses of Fe-inefficient plant species to agricultural S differ greatly and that banding applications of S or H/sub 2/SO/sub 4/ in calcareous soils in which only part of the soil is neutralized may result in correction of Fe deficiency in at least some species. Sulfuric acid sufficient to neutralize the CaCO/sub 3/ in 2 percent of the soil (all of the soil in the center of the pot) prevented Fe deficiency in PI54619-5-1 soybeans.
