Why is Sulphur Important?

Sulfur is essential for the formation of amino acids, which play a vital role in protein production. Not only is sulfur crucial for chlorophyll formation in leaves, but it is also an essential component of the synthesis of vitamins and enzymes for oil and protein in canola (Price, 2006).

How does including Super-S in a blend boost Sulphur Uptake?

Super S, 11-0-0-75, uses proprietary Shell Thiogro technology to produce a unique fertiliser in which micronised elemental sulphur is evenly dispersed through a urea matrix in each granule. This unique technology offers micronised sulphur that is
able to meet the crops immediate and long-term needs, whilst also providing a plant available source of nitrogen.
