Highly Concentrated Potassium Fulvic Acid Hollow Particle For Soil Enhancement
Highly Concentrated Hollow Particle of Potassium Fulvate Fulvic Acid ≥50% 100% Water Soluble Technology
Product Description:
Our potassium fulvate hollow granules are made from lignite and weathered lignite using a high-tower spray drying process.The hollow particles feature a porous outer shell and a hollow inner cavity, which not only increases the specific surface area for better nutrient adsorption and release but also enhances water retention and soil aeration. It ensures uniform dispersion in soil or water-based systems, avoiding clumping . Free from heavy metals, harmful pathogens, and synthetic additives, it aligns with global organic agriculture standards, making it a safe choice for both conventional and organic farming, as well as environmental remediation projects.
Product Functions:
1. Soil Health Enhancement: The hollow particles penetrate deep into the soil, loosening compacted soil layers and improving soil structure. They stimulate the reproduction of beneficial microorganisms (such as rhizobia and mycorrhizal fungi), enhancing soil fertility and reducing soil-borne diseases. Additionally, the porous shell absorbs excess salts in saline-alkali soils, regulating soil pH and creating a favorable growth environment for crops.
2. Efficient Nutrient Absorption & Utilization: As a natural chelating agent, potassium fulvate in the hollow particles binds to essential nutrients (such as nitrogen, phosphorus, potassium, iron, zinc, and manganese), converting them into forms that are easily absorbed by crop roots. The hollow cavity also acts as a "nutrient reservoir," releasing nutrients slowly and continuously throughout the crop growth cycle, ensuring long-term nutrient supply and preventing nutrient deficiency or excess.
3. Stress Resistance & Crop Quality Improvement: The bioactive components in the product enhance crop resilience to various environmental stresses, including drought, waterlogging, high/low temperatures, and pest infestations.
4. Environmental Protection & Sustainability: By reducing the need for chemical fertilizers and pesticides, Potassium Fulvate Hollow Particle minimizes agricultural non-point source pollution, protecting groundwater and ecological systems.

Applications:
1. Field Crops: Ideal for rice, wheat, corn, cotton, soybeans, and other staple crops. Applied during sowing (as a seed treatment or base fertilizer) or during key growth stages (as a topdressing or foliar spray), it improves yield by 10-15% and enhances crop resistance to adverse weather conditions.
2. Cash Crops: Highly effective for fruits (apples, oranges, grapes, strawberries), vegetables (tomatoes, cucumbers, peppers), and economic plants (tobacco, tea, medicinal herbs). It enhances fruit coloring, increases sugar content, and reduces the incidence of physiological diseases (such as blossom-end rot in tomatoes).
3. Horticulture & Turf Management
4. Greenhouses & Nurseries: Used in soilless culture (hydroponics, substrate culture) or potted plants, it provides balanced nutrients and improves subst
