Read: 14

Product Overview

Mineral Source Potassium Fulvate is a premium water-soluble organic fertilizer derived from high-grade Leonardite (oxidized lignite) or weathered coal. It undergoes millions of years of natural geological processes, resulting in a highly concentrated, biologically active substance. It is widely recognized as the "king of organic fertilizers" due to its unique molecular structure and superior chelating capabilities.

CAS No.: 479-66-3 (Fulvic Acid)

Appearance: Shiny black flakes or powder

Water Solubility: 100%

HS Code: 3101001900 (Organic Fertilizers)

Main Markets: Greenhouse vegetables, fruits, cash crops, turf, and organic farming.

Key Features & Composition

  • Active Ingredients: Contains High Purity Fulvic Acid (≥50%), Water-soluble Potassium (K₂O ≥12%), and naturally occurring trace elements (Fe, Zn, Mn, etc.).

  • Small Molecular Weight: Ultra-small molecules that can easily penetrate plant cell walls, ensuring rapid absorption and translocation within the plant.

  • Rich Functional Groups: Possesses a high density of carboxyl, hydroxyl, and phenolic hydroxyl groups, which give it strong chelating, adsorption, and ion-exchange abilities.

  • 100% Water Soluble: Dissolves instantly without any residue, making it ideal for drip irrigation and foliar spray systems.

Mechanism of Action & Benefits

A. Soil Improvement

Soil Structure: Promotes the formation of soil aggregates, preventing soil hardening and improving soil porosity and aeration.

PH Buffering: Effectively regulates soil pH and buffers soil salinity.

Microbial Activity: Provides a carbon source for beneficial soil microorganisms, enhancing soil fertility and suppressing soil-borne pathogens.

B. Plant Growth Promotion

Root Development: Stimulates root cell division, promoting a robust root system for better nutrient uptake.

Nutrient Use Efficiency (NUE): Chelates insoluble nutrients (P, K, Ca, Mg, Fe, Zn) in the soil, converting them into forms easily absorbed by crops, thus reducing fertilizer loss.

C. Stress Resistance & Quality

Drought & Cold Resistance: Induces the production of stress-resistant proteins and sugars, helping crops withstand drought, cold, and saline-alkali conditions.

Yield & Quality: Enhances photosynthesis, promotes fruit coloring, increases sugar content (Brix), and improves fruit firmness and shelf life.

Application Methods

  • Drip Irrigation / Flushing: 100-200 grams per acre per application.

  • Foliar Spray: Dilute 1000-1500 times.

  • Base Fertilizer Mixing: Mix with NPK fertilizers or organic fertilizers (Recommended dosage: 500-1000 grams per acre).
