Potassium Fulvate

Potassium fulvate is a highly bioactive, water-soluble fraction of humic substances, derived from decomposed organic matter (like leonardite or peat). It is rich in fulvic acid, minerals, and trace elements, making it a powerful soil conditioner and plant growth enhancer.

Benefits of Potassium Fulvate in Agriculture

For Plants
Boosts Nutrient Absorption – Chelates minerals (N, P, K, Ca, Mg, Fe, Zn) for better uptake.
Stimulates Root Growth – Enhances root elongation and branching.
Improves Stress Tolerance – Helps plants resist drought, salinity, and disease.
Enhances Chlorophyll Production – Leads to darker green leaves and better photosynthesis.
Increases Yield & Fruit Quality – Promotes flowering, fruit setting, and sugar content.

For Soil
Improves Soil Structure – Prevents compaction and enhances aeration.
Increases Microbial Activity – Supports beneficial bacteria & fungi.
Detoxifies Soil – Binds heavy metals and pesticides.
Balances pH – Buffers acidic or alkaline soils.

Potassium Fulvate vs. Humic Acid vs. Fulvic Acid

Property	Potassium Fulvate	Humic Acid	Fulvic Acid
Solubility	Water-soluble	Alkali-soluble	Water-soluble
Molecular Size	Small	Large	Very small
Nutrient Uptake	High (due to chelation)	Moderate	Very High
Soil Improvement	Good	Excellent	Limited
Best For	Foliar spray, hydroponics	Soil conditioning	Rapid nutrient absorption

Potassium Fulvate = Fulvic Acid + Potassium (More bioavailable than humic acid).

Applications & Usage Methods

Application	Method	Dosage
Seed Soaking	Soak seeds in diluted solution (0.5-1g/L)	4-12 hours
Foliar Spray	Apply diluted solution (1-3g/L)	Every 10-15 days
Drip Irrigation	Mix with irrigation water (2-5kg/acre)	Every 2-3 weeks
Soil Drench	Apply directly to soil (3-5kg/acre)	At planting & growth stages
Hydroponics	Add to nutrient solution (50-100ppm)	Continuously
