Sulfur is a constituent of three amino acids (cystine, methionine, and cysteine) and is therefore essential for protein synthesis. It is essential for nodule formation on legume roots. (Western Fertilizer Handbook)

General symptoms of sulfur deficiency in plants include:
  • Young leaves light green to yellowish color. 
  • In some plants, older tissue may be affected also.
  • Small and spindly plants.
  • Retarded growth rate and delayed maturity.
