K-HUMATE S100
70% Humic Acid. Granular. Soluble. Powerful.
The granular and water-soluble form of Omnia's proven K-HUMATE humic acid technology — delivering 70% humic acid and 21% potassium for broadcast, band, or fertigation programs where liquid application is not practical.
What is K-HUMATE 26?
K-HUMATE 26 is Omnia USA's core liquid humic acid product. A high-concentration liquid soil conditioner formulated to improve soil biology, structure, and nutrient-use efficiency. Registered with the California Department of Food and Agriculture (CDFA), K-HUMATE 26 is verified at 20% humic acid and 6% soluble potash (K₂O), providing both biological soil benefits and direct potassium nutrition in a single application.
K-HUMATE 26's CEC (cation exchange capacity) rating of 1,900 meq/100g is one of the highest in the market, meaning it has an exceptional ability to hold and exchange nutrients in the root zone, reducing leaching losses and improving fertiliser return on investment.
How K-HUMATE 26 Works
- Increases CEC: Humic acid's high CEC improves the soil's capacity to hold cations (Ca, Mg, K, NH4+) in the root zone, reducing losses to leaching.
- Improves NUE: More nutrients stay where roots can access them, reducing the fertiliser input needed to achieve the same crop performance.
- Stimulates root growth: Humic acids chelate micronutrients and increase their bioavailability, promoting denser, more active root systems.
- Reduces nutrient lock-up: In high-pH or highly alkaline soils, K-HUMATE 26 improves the solubility of phosphorus, iron, zinc, and manganese.
- Salt tolerance: Regular use helps buffer soil salinity, reducing salt stress in crops grown in high-sodium soils common in CA, AZ, and FL.
- Supports soil biology: Humic acids are a carbon energy source for soil microbial communities. Regular application builds biological activity over time.

FAQ
What is the difference between K-HUMATE 26 and K-HUMATE S100?
K-HUMATE 26 is a liquid (9.17 lbs/gal) with 20% humic acid and 6% K₂O — ideal for fertigation and foliar. K-HUMATE S100 is a granular/soluble form with 70% humic acid and 21% K₂O — preferred for broadcast application, dry fertilizer blending, or operations where liquid handling is not practical. Both products deliver the same soil-improving benefits; the choice is determined by your equipment and application program.
