Usage Scenarios
1. High-Value Horticulture
Widely used for container-grown plants (nursery stock, ornamentals, vegetables), greenhouse crops, and turfgrass (golf courses, sports fields, lawns) where precise nutrition and reduced labor are critical.
2. Large-Scale Field Crops
Increasingly adopted for staple crops like corn, rice, and wheat, especially in regions prone to leaching or where labor costs are high, improving efficiency and yield stability.
3. Sandy Soils & High Rainfall Areas
Particularly beneficial in soils with low nutrient retention or areas with heavy rainfall, where conventional fertilizers are easily washed away.
4. Long-Season Crops & Perennials
Ideal for fruit trees, vineyards, and other crops with extended growing seasons needing sustained nutrition.
5. Precision Agriculture & Reduced Access Areas
Useful where frequent field access for top-dressing is difficult, expensive, or undesirable. Simplifies fertilization programs.
Frequently Asked Questions
What are the benefits of using controlled-release compound fertilizer?
It promotes root absorption, enhances crop resistance, prevents trace element deficiencies, and optimizes photosynthesis. Additionally, its balanced nutrition formula ensures uniform nutrient release and a durable fertilizing effect.
What is the granular quality and size of this fertilizer?
The fertilizer features a perfect granular design, with 90% of the granules sized between 1-4 mm. It delivers highly available phosphate (80% water-soluble) and guarantees even nutrients in every single granule.
What crops and conditions is this fertilizer best suited for?
It is ideal for high-value horticulture (greenhouse crops, turfgrass, ornamentals), large-scale field crops (corn, rice, wheat), sandy soils, high rainfall regions prone to nutrient leaching, and long-season perennial crops.
How does it perform in terms of yield increase?
Field data shows remarkable yield improvements, with average yield increases of 8.3% on corn, 9.8% on rice, and 12.5% on tomato crops, respectively.
Are there low chloride options available?
Yes, the fertilizer is available in low chloride options (with potassium sourced from SOP) as well as MOP base formulas to accommodate different crop sensitivities.
