Correction of lime-induced chlorosis in soybeans in a glasshouse with sulfur and an acidifying iron compound
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.
