Product Overview
Potassium Humate is a highly effective organic potassium fertilizer extracted from high-grade leonardite. It is 95% water-soluble and combines humic acid with potassium to improve soil structure, enhance nutrient uptake, and stimulate plant growth.
This product acts as both a soil conditioner and a nutrient booster. It helps chelate micronutrients, increases the cation exchange capacity (CEC) of soil, and improves water retention. Suitable for a wide range of crops, including grains, vegetables, fruits, and ornamentals.
Molecular formula: C9H8K2O4
Relative molecular mass: 258.35
Appearance: Black flakes, powder or granules
Key Features & Benefits of Natural Potassium Humate-Improve Soil Fertility Boost Nutrient Uptake
- Soil Improvement: Enhances soil structure, increases aeration, and promotes microbial activity.

Agricultural & Horticultural Uses
The primary uses of potassium humate are in agriculture and horticulture, where it acts as a plant growth stimulant and soil conditioner. Natural Potassium Humate-Improve Soil Fertility Boost Nutrient Uptake . It’s derived from natural sources like leonardite and is used to improve crop growth without having any pesticidal activity itself .
As a Biostimulant: It is extensively studied for its efficacy as a biostimulant. It has been shown to increase the biomass of various crops, improve water use efficiency, and enhance yields, particularly under stress conditions like drought . For example, studies on foxtail millet show that potassium humate application can increase photosynthetic rate and yield by over 12% . It has also been proven to increase potato tuber yields by up to 80% in some trials .
Application Methods: It is highly versatile in how it can be applied. It is suitable for use on all crops, including vegetables, fruits, ornamentals, turf, and broadacre crops . Common application methods include :
- Foliar Spray: Applied directly to plant leaves.
- Fertigation / Drip Irrigation: Added to irrigation systems.
- Soil Application: Applied directly to the soil or in-furrow during planting.
- Seed Treatment: Used as a seed dressing to promote early root growth.
- Fertilizer Additive: It is often used as an additive in fertilizers. It acts as a natural chelator, binding to essential micronutrients like iron, zinc, and manganese, which makes them more accessible to plant roots and prevents nutrient deficiencies .
