Potassium Fulvate Powder – Premium Humic & Fulvic Acid Fertilizer for Thriving Plants

Our Potassium Fulvate Powder is a high-quality, nutrient-dense solution designed to meet the needs of professional farmers, gardeners, and horticulturists. Packed with ≥5% Fulvic Acid and ≥70% Humic Acid, this powder is a natural organic fertilizer and plant growth booster, formulated to enhance soil fertility, promote robust root development, and support healthy, vigorous plant growth.

Powerful Nutrient Composition

This premium water-soluble fertilizer combines the benefits of humic and fulvic acids with essential potassium:

  • Fulvic Acid ≥5% – Low molecular weight compounds act as natural chelators, binding to nutrients and making them readily available for plant absorption.

  • Humic Acid ≥70% – Improves soil structure, increases water retention, and enhances cation exchange capacity.

  • Potassium (K₂O) ≥12% – Supports strong stems, vibrant foliage, flowering, and fruit development.

With a pH of 8.0–11.0 and moisture ≤15%, the powder is stable, easy to store, and ready for immediate use.

Benefits for Agriculture & Soil Health

Our Potassium Fulvate Powder is more than just a fertilizer—it’s a complete soil conditioner and plant enhancer:

  • Enhances Nutrient Uptake – Fulvic acid chelates micronutrients such as iron, zinc, boron, and manganese, ensuring efficient absorption by plants.

  • Stimulates Root Development – Promotes healthy, deep root systems for better water and nutrient uptake.

  • Boosts Plant Vigor – Encourages strong stems, lush foliage, abundant flowers, and high-quality fruit.

  • Improves Soil Structure – Humic acid increases soil porosity and water retention, creating a fertile environment for roots.

  • Supports Microbial Activity – Stimulates beneficial soil microbes, improving soil health and sustainability.

This fertilizer is suitable for a wide range of crops, including vegetables, fruits, grains, flowers, and ornamental plants, making it ideal for large-scale farms, greenhouses, and home gardens.

Easy Application

Our Potassium Fulvate Powder is 100% water-soluble, allowing for quick and uniform nutrient delivery. Application methods include:

  • Soil Drenching – Dissolve in water and apply directly to the root zone for optimal nutrient uptake.

  • Foliar Spray – Mix with water and spray onto leaves for rapid absorption.

  • Hydroponic Systems – Compatible with soilless cultivation for maximum plant growth.

These flexible application options make it simple to integrate into any planting or gardening program.

Rate guidance: the rate depends on crop, growth stage and whether you spray, drench or apply to soil. Tell us the crop and the application method you use and we will send the rate for this grade.

Choosing between the fulvic and potassium fulvate grades

Humic acid improves soil structure; fulvic acid is the low molecular weight fraction that chelates nutrients. The ratio between them is the main difference between these four grades.
