Sulfer deficiency in soils

There is no doubt of the importance, in plant and animal economy, of sulfur as a synthate for proteins and a number of other essential or important organic compounds. Sulfur undoubtedly is needed in considerable quantities in a number of deficient soils in the United States and other countries, especially in regions distant from industrial and population centers where relatively little sulfur is furnished by the air. Any permanent fertilizer system that does not include the application of a sulfur-carrier is sure to result in sulfur-hungry crops in some rural regions.
