ZnZinc Zinc is essential in a wide range of plant functions as an enzyme co-factor, in protein synthesis and protein structure, hormone regulation, early root development, energy production and is key for seed formation.

SSulphur Sulphur has many critical functions in the plant including: Formation of chlorophyll essential for photosynthesis. The majority of sulphur in crops is as a constituent of three S-containing amino acids (cysteine, cystine and methionine), which are the building blocks of protein. It is important for yield and crop quality, and essential for enzyme activation, nitrogen metabolism and in oilseeds it is crucial for oil synthesis.

Zinc shortages will result in:

  1. Shortened internodes.
  2. Stunted plants/leaves.
  3. Reduced seed set.
