Potassium humate is the potassium salt of humic acid, produced from high-grade leonardite or lignite through alkaline extraction.
It combines high humic acid content with potassium (K₂O), making it both a soil conditioner and a plant nutrient source.
Its 100% water solubility and strong chelating ability make it ideal for fertigation, foliar spraying, and direct soil application in modern agriculture.
Enhances cation exchange capacity (CEC) for better nutrient retention.
Improves soil structure, aeration, and water-holding capacity.
Chelates trace elements (Fe, Zn, Cu, Mn) for better plant availability.
Reduces leaching losses of nitrogen and potassium.
Promotes root elongation and lateral root development.
Enhances chlorophyll synthesis, boosting photosynthesis.
Improves plant tolerance to drought, salinity, and temperature stress.
Keeps nutrients soluble and prevents precipitation in solution.
Dual Benefit: Supplies organic humic acid and potassium together.
High Solubility: Easy application in irrigation or foliar sprays.
Eco-Friendly: Natural, biodegradable, and safe for long-term soil use.
Fertilizer Synergy: Works with NPK and trace element fertilizers.
Yield & Quality Improvement: Enhances crop productivity and quality.

Q1: How is potassium humate different from humic acid sodium salt?
A1: Potassium humate provides essential potassium along with humic acids, while sodium humate is used mainly for soil structure improvement and certain feed applications.
Q2: Can it be used with all fertilizers?
A2: Yes, it is compatible with most fertilizers and pesticides, except strong acids.
Q3: Is it suitable for organic farming?
A3: Yes, if sourced from natural leonardite and processed without synthetic chemicals.
Q4: Can it be applied via foliar spray?
A4: Yes, it is highly effective when absorbed through leaves, especially during growth stages.
Q5: Does it improve crop yield?
A5: Yes, by enhancing nutrient uptake, photosynthesis, and stress resistance.
