Sulfuric acid and ferrous sulfate treatnients of calcareous soil increased yields of hybrid grain sorghum grown in the greenhouse. Effects of 250 ppm or more Fe with 250 ppm or more H 2 SO 4 were still significant on the third crop after soil treatments were made. This study shows that residual effects are possible from heavy applications of FeSO 4 and H 2 SO 4 . In a field experiment, 560 kg/ha iron as FeSO 4 or 560 kg/ha of H 2 SO 4 produced about the same yield response on calcareous Arch Fine sandy loam.
