Potassium fulvate hollow granules are an advanced fertilizer formulation manufactured using innovative spray drying technology, designed for optimal performance and ease of use.

This process employs a high-tower spray drying method. A concentrated potassium fulvic acid solution is sent to the top of the tower, where it is sprayed into fine droplets. These droplets rapidly evaporate moisture upon contact with hot air, forming hollow spherical particles with tiny pinholes on their surface.

• Rapid Dissolution: Hollow structure enables quick disintegration in water with complete solubility and no residue
• Enhanced Activity: Low-temperature processing preserves biological activity for optimal soil conditioning
• Superior Flowability: Uniform, sand-like particles prevent clumping and support mechanized application
• Soil Adaptability: Large surface area absorbs nutrients and water while regulating soil pH and structure

• Soil Enhancement: Promotes aggregate formation, reduces compaction, and improves aeration and water retention
• Root Development: Stimulates cell division and elongation for stronger, more extensive root systems
• Disease Resistance: Supports beneficial microorganisms to combat soil-borne diseases and continuous cropping issues
• Yield Improvement: Enhances photosynthesis, nutrient conversion, fruit quality, and overall crop productivity

Suitable for a variety of crops, including fruit trees, vegetables, melons, medicinal plants, seedlings, flowers, and field crops. Particularly effective for compacted, acidified soils and those subjected to continuous cultivation.

Hollow potassium humic acid granules combine the excellent properties of potassium humic acid with the practical advantages of hollow granule technology. This highly efficient and environmentally friendly fertilizer can significantly improve soil health and increase crop yield, making it an ideal choice for modern agriculture seeking continuous improvement in both yield and quality.
