Engineered for high-efficiency farming and elite landscaping standards.
The United States stands as one of the most sophisticated markets for slow-release fertilizers (SRF) and controlled-release fertilizers (CRF). Driven by the dual pressures of maximizing crop yields in the "Corn Belt" and adhering to stringent environmental regulations regarding nutrient runoff—particularly in sensitive regions like the Chesapeake Bay and the Florida Everglades—US agriculture is undergoing a massive shift toward precision nutrition.
Leveraging 18 years of specialized expertise in nutrient engineering.
Our facility covers an expansive 300,000 square meters with an annual production capacity reaching 300,000 Metric Tons. This scale ensures a stable supply chain for large-scale North American agricultural distributors.
Equipped with 2 high-tower granular lines, rotary drum lines, and dedicated systems for Potassium Sulphate and Magnesium Sulphate, we produce high-purity nutrients tailored for American soil profiles.
Since establishing our first NPK line in 2008, we have evolved into a modern enterprise with independent research and design ability, ensuring our slow-release formulas match the latest precision ag-tech requirements.
The application of slow-release fertilizers in the United States is segmented into four primary industrial categories, each requiring specific chemical formulations and release profiles:
In states like Iowa, Illinois, and Nebraska, nitrogen leaching is a major concern. Farmers are increasingly adopting polymer-coated urea (PCU) which releases nitrogen based on soil temperature, matching the peak growth phases of corn. Our 20-10-20 NPK and 26-11-11 Resin Coated formulas are specifically designed to reduce the frequency of application, saving on fuel and labor costs while protecting local watersheds.
Management of elite golf courses in Florida, Arizona, and California demands ultra-consistent growth without "surge growth" spikes. Our Lvyin NPK 20-5-10 (180 Days) provides a steady nutrient stream for 6 months, ideal for the high-sand content soils of professional greens where traditional fertilizers would leach instantly.
For almonds, grapes, and berries, precision is key. Water-soluble slow-release fertilizers allow for fertigation systems that deliver micronutrients like Zinc and Magnesium in a controlled manner, preventing nutrient antagonism and ensuring fruit quality that meets stringent export standards.
The US residential market is seeing a surge in "DIY" lawn maintenance. Our 13-13-13 All-Purpose Slow Release granules are consumer-friendly, reducing the risk of "turf burn" and providing a "green-up" that lasts for an entire season with a single application.
While our fertilizers are widely exported to Japan, Korea, Vietnam, and across South America and the Middle East, our production standards are aligned with the Association of American Plant Food Control Officials (AAPFCO) guidelines. We specialize in:
