Ammonium Sulphate 21-0-0 – Nitrogen and Sulfur Fertiliser for Improved Growth

Ammonium Sulphate 21-0-0 is a widely used nitrogen and sulfur fertiliser, valued for its effectiveness in promoting healthy plant growth and improving soil nutrient balance. Containing 21% nitrogen and sulfur, it supports strong vegetative growth, improved leaf colour, and efficient protein formation in plants.

This fertiliser is especially beneficial for alkaline or sulfur-deficient soils, where sulfur availability can limit plant performance. In addition to feeding plants, ammonium sulphate helps slightly acidify the soil, improving nutrient availability in high-pH conditions.

Commonly used in agriculture, gardens, and lawns, ammonium sulphate provides reliable, fast-acting nutrition when plants need an immediate nitrogen boost. As a 21-0-0 formulation, it contains no phosphorus or potassium, making it ideal for targeted nitrogen and sulfur supplementation.
