Unlock Higher Crop Yields with Slow-Release Granular Ammonium Sulfate Technology

Unlock Higher Crop Yields with Sustained Nutrient Release Technology

Are you struggling to maintain consistent crop growth across seasons? Do traditional fertilizers fail to deliver the long-term nitrogen supply your fields need?

At Yunnan Yingfu Trading Co., Ltd., we’ve engineered a breakthrough in fertilizer technology—Granular Ammonium Sulfate (Sustained-Release Formula)—designed not just for immediate results, but for lasting productivity. Backed by field trials and real-world data from over 200 farms in China, Southeast Asia, and Africa, our product delivers up to 40% more nitrogen retention compared to standard granules—and that translates directly into higher yields and better soil health.

Why This Matters: The Science Behind the Yield Boost

Unlike conventional ammonium sulfate that releases nutrients rapidly within days, our patented coating ensures a controlled release over 4–6 weeks—ideal for rice, maize, cotton, and vegetables. According to a 2023 study published in the Journal of Agricultural Science & Technology, sustained-release nitrogen fertilizers increased grain yield by an average of 17–22% when applied at optimal rates during planting season.

Our formula combines high-purity nitrogen (21% N) with enhanced flowability and uniform particle size—critical for even distribution via mechanical spreaders or drip irrigation systems. Farmers report fewer clogs, less waste, and significantly improved root uptake efficiency.

Real Results, Real Farms

In Yunnan Province, a 150-hectare rice farm saw a 24% increase in yield after switching to our sustained-release granules. "The plants stayed greener longer," said farmer Li Wei. "We didn’t have to reapply every two weeks—we saved labor, time, and money."

Similarly, in Kenya’s Rift Valley, tomato growers using our product reported 18% higher fruit quality scores due to stable nutrient availability throughout the flowering and fruiting stages—a key factor in premium market pricing.

Tailored Solutions for Every Season

Whether it’s spring planting in temperate zones or dry-season cultivation in tropical regions, our granules adapt seamlessly. In summer heat, they reduce volatilization losses by up to 30%. In winter conditions, their slow-release mechanism prevents leaching—ensuring nutrients stay where they’re needed most.

What if your crops are stunted despite regular feeding? It might be not the amount—but how long the nutrients last. Our solution isn't just fertilizer—it's a strategy for smarter farming.

And because we know trust is earned, not assumed, every batch undergoes rigorous lab testing and comes with full traceability. From warehouse to field, quality control is built into every step of our global supply chain.
