The importance of Sulphur in your fertiliser
Whilst Nitrogen is a growth promoter, Sulphur works as a growth regulator, effectively balancing the manufacture of sugars and proteins in leaf tissue with the demand from these materials throughout the plant. Consequently, Sulphur plays a crucial role in maintaining green leaf area, growth rates and delaying senescence. Low Sulphur levels reduce Nitrogen metabolism, leaf expansion and plant development. The nutrient is very mobile in the soil meaning wet winters and early springs leave low reserves in the soil. Crops need a steady supply throughout rapid growing seasons, so it’s key to apply S each time N is applied in your fertiliser.
