Every thriving garden, farm, or lawn needs the right nutrients to flourish, and ammonium sulphate and urea deliver unmatched results. With ≥20.5% nitrogen and ≥23.5% sulphate, this powerful combination fuels rapid plant growth while improving soil health. Unlike single-nutrient fertilizers, ammonia sulphate fertiliser provides dual benefits—nitrogen for lush greenery and sulphur for stronger root development. Whether you're growing crops, maintaining a golf course, or nurturing a backyard lawn, ammonia fertilizer for grass ensures deep, vibrant growth without harmful residues. Its low moisture (≤1.5%) and free acid (≤0.05%) content make it gentle on plants while maximizing efficiency.

Why Choose Ammonium Sulphate Nitrogen for Your Lawn? 

If you want a lawn that stays green and resilient all year, ammonium sulfate nitrogen is the perfect solution. The granular form (2-5mm) ensures even spreading, preventing patchy growth and nutrient waste. Unlike liquid fertilizers that evaporate quickly, urea ammonium sulphate releases nutrients steadily, feeding grass roots over time. The white granules (with optional OEM colors for easy identification) dissolve efficiently in water, making them ideal for both direct application and irrigation systems. Farmers and landscapers trust ammonia sulphate fertiliser because it’s safe, effective, and free from insoluble impurities (≤0.5%). For lawns that demand premium care, this is the go-to choice.

The Dual Power of Urea Ammonium Sulphate 

Why settle for one nutrient when you can get two? Urea ammonium sulphate combines fast-acting nitrogen with essential sulphur, creating a balanced fertilizer that promotes vigorous plant growth. The high nitrogen content (≥20.5%) ensures rapid greening, while sulphur boosts chlorophyll production and stress resistance. This makes ammonia fertilizer for grass especially valuable in sulphur-deficient soils, where plants often struggle. The granular structure (90% within 2-5mm) allows for precise application, whether by hand or machine. Plus, with ≤1.5% moisture, it stores well without clumping. For farmers, turf managers, and gardeners, ammonium sulphate and urea offer a cost-effective way to maximize yields and beauty.

How to Apply Ammonia Sulphate Fertiliser for Best Results 

Getting the most from your ammonia sulphate fertiliser is simple with the right approach. For lawns, broadcast the granules evenly using a spreader, then water lightly to activate nutrient release. In agriculture, apply before planting or during growth stages, ensuring even distribution to avoid over-concentration. The low free acid content (≤0.05%) means ammonium sulfate nitrogen won’t harm plants, even with frequent use. For best results, pair with regular soil testing to adjust application rates. Whether you’re maintaining a sports field or a home garden, urea ammonium sulphate ensures consistent, reliable growth without guesswork.

Eco-Friendly and Efficient: The Smart Choice 

Sustainability matters, and ammonium sulphate and urea deliver outstanding results without harming the environment. With minimal insoluble residues (≤0.5%) and no toxic additives, this fertilizer is safe for waterways, pets, and wildlife. The high nutrient efficiency means less product is needed over time, reducing waste and cost. Unlike synthetic blends, ammonia fertilizer for grass supports long-term soil health by replenishing sulphur—a key element often overlooked in conventional fertilizers. By choosing urea ammonium sulphate, you’re investing in greener growth for your plants and the planet.

FAQs About Ammonium Sulphate Nitrogen 

How often should I apply ammonia sulphate fertiliser? 

For lawns, apply ammonium sulfate nitrogen every 4-6 weeks during growing seasons. Adjust based on soil tests and plant response.

Can I mix urea ammonium sulphate with other fertilizers? 

Yes, but conduct a small test first. Our ammonia sulphate fertiliser is compatible with most blends but avoid high-lime products.

Is ammonia fertilizer for grass safe for pets? 

Once watered in, it’s pet-safe. Keep animals off the lawn until granules dissolve (usually after rain or irrigation).

What’s the shelf life of ammonium sulphate and urea?

Stored in a dry place, urea ammonium sulphate remains effective for years. Avoid moisture to prevent clumping.
