About This Product

Ammonium Sulphate (21-0-0) is a fast-acting, highly soluble crystalline inorganic salt fertilizer that delivers an immediate supply of nitrogen alongside essential sulfur. Because it has an acidifying effect on the rhizosphere, it is exceptionally valuable for treating alkaline soils and meeting the demands of sulfur-loving crops.

Technical Composition

Ammonium Nitrogen (N): 21%, Sulphur (S) as Sulphate: 24%

Key Benefits
  • Provides quick-release nitrogen in the readily available ammonium form to spark deep green vegetative flushes
  • Delivers a massive dose of sulphate sulfur, a vital component driving fundamental chlorophyll and protein synthesis
  • Lowers the local soil pH environment effectively, making locked-up micronutrients available in alkaline or high-pH soils
  • Promotes the growth and colonization of beneficial, native soil microbes to support long-term underground health
Recommended Dose

Foliar Spray: 6–7 g per litre of water (or a maximum 2% solution). Direct Soil Application: 4–5 g per plant near the root zone, or 20–50 kg per acre for broadacre farming.
