Soybeans were grown in calcareous Hacienda loam soil in which small quantities of amendments to correct iron chlorosis were placed. The amendments used were combinations of sulfur and a waste iron product containing a crystalline form of sulfuric acid. Mixtures of sulfur and the acidifying material produced better prevention of the lime-induced chlorosis than did either product alone. Suggested is that the sulfur-oxidizing bacteria function more efficiently when calcareous soil is acidified than in the original soil. Most effective results were obtained with rates equivalent to 370 kg/ha for the acid iron waste product. Treatment with 185 kg/ha of elemental sulfur gave little response. Control was 24% of maximum response. Iron uptake per plant in leaves was highly correlated with yield, but iron concentration in leaves was not.
