Ammonium Sulfate

Properties:

• High bulk density maximizes bin space
• Coated with anti-caking agent to maintain ease of handling
• Can also be directly applied

Application Methods

• Broadcast (dry surface application)

Advantages

• Sulfur deficiencies have become more common, mainly due to the use of sulfur-free fertilizers, higher crop yields and reduced sulfur emissions.
• Like nitrogen, microorganisms will immobilize sulfur to balance their carbon-to-sulfur ratio.
• This can also contribute to a sulfur deficiency, especially under conservation tillage practices where crop residues accumulate on the soil surface.

Disadvantages

• Sulfur deficiencies can be visually observed.
• Plants deficient in sulfur show a pale green coloring of younger leaves — not to be confused with nitrogen deficiency found on older leaves.
