Product Description
High-Quality Slow Release Compound Fertilizer
Slow Release Compound Fertilizer is a premium NPK fertilizer designed to provide balanced nutrition for healthy crop growth. Manufactured by Shandong Aolansu Environmental Protection Technology Co., Ltd., it is produced using advanced resin coating technology and high-quality raw materials. The product complies with GB/T 23348-2009 and ISO 18644:2016, ensuring stable quality, safety, and environmental friendliness.
Controlled Nutrient Release
The resin-coated granules gradually release nitrogen, phosphorus, and potassium according to crop growth stages, reducing nutrient loss while improving fertilizer utilization. Compared with conventional fertilizers, it helps reduce fertilizer applications, lowers labor costs, and supports healthier plant growth with higher yield potential.
Wide Range of Applications
Suitable for rice, wheat, corn, soybeans, vegetables, fruit trees, cotton, tea, potatoes, and other crops. It performs well in acidic, neutral, and alkaline soils and can be applied by broadcasting, furrow application, hole application, or drip irrigation.
Reliable Quality & Supply
Produced under strict quality control, each batch is tested to ensure consistent nutrient content and coating performance. As a professional manufacturer and supplier in China, Aolansu offers factory-direct pricing, stable production capacity, flexible orders starting from 1 ton, and customized packaging solutions for global customers.
Packaging & Storage
Available in 25 kg woven bags, 50 kg drums, and 1000 kg jumbo bags, with OEM packaging available upon request. Store in a cool, dry, and well-ventilated place to maintain product quality during storage and transportation.

FAQ
Q1: What is the difference between Slow Release Compound Fertilizer and traditional quick-release compound fertilizer?
A1: The biggest difference lies in the nutrient release mode. Traditional quick-release compound fertilizer releases nutrients rapidly, which easily causes nutrient loss through leaching and volatilization, and may lead to fertilizer burn. Our slow-release compound fertilizer adopts resin coating technology to control nutrient release rate, which matches the crop growth cycle, with higher nutrient utilization rate (more than 45%), fewer fertilization times and labor-saving advantages. It also avoids environmental pollution caused by nutrient loss.
Q2: Can the nutrient release period of the product be customized according to our needs?
A2: Yes. As a professional China manufacturer, Aolansu can customize the nutrient release period (3-12 months) according to the specific growth cycle of your local crops and soil conditions, ensuring that the nutrient supply perfectly matches the crop growth needs and maximizing the fertilization effect.
