To make potassium humate at home or commercially, follow these steps:
Obtain Raw Material: Use a rich source of humic acid, such as leonardite or lignite coal.
Alkaline Extraction: Soak the material in a strong alkali solution like potassium hydroxide (KOH) to dissolve humic acids from the coal. Use protective equipment for safety.
Filtration: Filter the resulting solution to remove undissolved particles and impurities.
Concentration: Concentrate the solution by evaporating excess water, especially for commercial production.
Drying (optional): For powdered potassium humate, dry the concentrated solution to form granules or powder. Alternatively, leave it in liquid form for fertigation or foliar applications.
This process creates an organic potassium humate product that can be used in agriculture.
