SULFUR DEFICIENCY IN SOILS

Abstract
There is no doubt of the importance of sulfur in plant and animal economy as a synthate fpr proteins and a number of other essential or important organic compounds. Amongst these are methionine. an essential, cystine and cysteine, 2 other amino acids, the two vitamins, B1 and biotin, and a large number of organic compounds peculiar to the mustard family and a number of other families of plants. Not only is sulfur needed in considerable quantities by organisms, but it is deficient for crop needs in many soils in U. S. and other countries, especially in regions distant from industrial and population centers where relatively little sulfur is furnished through the air. Any fertilizer system that does not include a sulfur-carrier is sure to result in sulfur-hungry crops in many rural regions.
