Usage Scenarios
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.
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.
Particularly beneficial in soils with low nutrient retention or areas with heavy rainfall, where conventional fertilizers are easily washed away.
Ideal for fruit trees, vineyards, and other crops with extended growing seasons needing sustained nutrition.
Useful where frequent field access for top-dressing is difficult, expensive, or undesirable. Simplifies fertilization programs.
Frequently Asked Questions
It improves root adhesion and increases trace element absorption. This helps prevent crop deficiencies while enhancing photosynthesis for stronger overall crop resistance.
It is available in either a low chloride base (potassium sourced from SOP) or a standard MOP base to suit different crop sensitivities.
The fertilizer features a perfect granular formulation with 90% of the granules sized between 1-4 mm. It contains highly available phosphate, of which 80% is water-soluble.
In sandy soils with low nutrient retention or regions with heavy rainfall, conventional fertilizers leach easily. This controlled-release formula prevents nutrients from being washed away, ensuring stable nutrition.
Field results show average yield increases of 8.3% on corn, 9.8% on rice, and 12.5% on tomatoes, along with reduced bare tip rates in corn.
