Potassium Fulvate Flakes – Premium Humic & Fulvic Acid Fertilizer for Optimal Plant Growth

Our Potassium Fulvate Flakes are a must-have solution for professional farmers, gardeners, and horticulturists who demand superior results. These black, 2–4 mm flakes are packed with essential nutrients and bioactive compounds, designed to improve soil health, boost plant growth, and enhance overall crop productivity.

Nutrient-Rich Composition

This high-quality water-soluble fertilizer contains a powerful combination of humic substances and potassium:

  • Humic Acid ≥60% – Improves soil structure, enhances water retention, and stimulates microbial activity.

  • Fulvic Acid ≥30% – With its low molecular weight, it chelates nutrients effectively, making them more bioavailable for plants.

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

With a pH range of 9.0–11.0 and moisture ≤12%, these flakes are stable, easy to store, and ready for immediate use in multiple applications.

Benefits for Soil and Plants

Our Potassium Fulvate Flakes act as a natural organic plant booster and soil conditioner, providing a range of advantages:

  • Enhances Soil Structure – Humic acid improves soil porosity, cation exchange capacity, and overall fertility.

  • Boosts Root Development – Fulvic acid and potassium stimulate vigorous root growth for better nutrient and water uptake.

  • Increases Nutrient Availability – Fulvic acid chelates micronutrients, ensuring plants absorb the nutrients they need efficiently.

  • Improves Stress Resistance – Strengthens plants against drought, cold, disease, and pest challenges.

  • Promotes Yield and Quality – Encourages healthy stems, vibrant blooms, and abundant fruit production.

Easy Application

Our Potassium Fulvate Flakes are 100% water-soluble, ensuring quick absorption by plants. They can be applied in a variety of ways:

  • Soil Drenching – Ideal for enriching the root zone and enhancing soil fertility.

  • Foliar Spray – Delivers nutrients directly to the leaves for rapid uptake.

  • Hydroponic Systems – Fully compatible with soilless cultivation for maximum growth.

These flakes are suitable for vegetables, fruits, flowers, cereals, and ornamental plants, making them versatile for both commercial farming and home gardening.

How it is applied

  • Soil drenching — enriches the root zone
  • Foliar spray — for rapid leaf uptake
  • Hydroponic systems — fully compatible with soilless cultivation

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.
