2.5 K in a Nutshell...
Enhances Your Product!
2.5 K enhances your products by combining the soil-conditioning power of humic acids with the nutrient boost of soluble potassium, improving nutrient availability, uptake, and overall soil fertility. Its enhanced solubility allows it to blend seamlessly into dry fertilizer formulations, making it ideal for boosting performance in broadcast, in-furrow, or custom blended applications. The humic acids promote root development, microbial activity, and cation exchange capacity, while the potassium supports plant resilience, water regulation, and stress tolerance—delivering a more complete, efficient, and agronomically advanced product.
Benefits Your Bottom Line!
2.5 K improves your ROI by enhancing the effectiveness of your existing fertilizer programs, allowing for more efficient nutrient use and reducing input waste. Its humic acid content increases nutrient retention in the root zone, meaning plants absorb more of what you apply—leading to stronger yields with less fertilizer. The added potassium supports healthier, more resilient crops, reducing the risk of loss due to drought, disease, or stress. By improving soil structure and long-term fertility, 2.5 K also contributes to sustainable productivity, making each application more cost-effective and delivering greater returns season after season.

Boost Plant Growth and Yield with 2.5 K
Why 2.5 K?
2.5 K is a high-performance, enhanced-solubility potassium humate derived from naturally oxidized leonardite sourced from the Fruitland Formation in Northwestern New Mexico. This dry, ready-to-use humate is ideal for incorporation into the soil or for blending with other dry fertilizers and inputs across a wide range of industries.
In agriculture, 2.5 K helps improve nutrient use efficiency and supports stronger root development, leading to healthier plants, increased yields, and better resistance to stress and drought. In turf care, it enhances nutrient uptake, improves color, encourages uniform growth, and promotes long-term turf vigor without the burn risk of traditional synthetics—ideal for golf courses, sports fields, and landscaping professionals. For horticulture, it supports more vibrant blooms, healthier foliage, better transplant success, and improved soil tilth, making it a preferred choice in greenhouse and nursery production. In soil remediation, its humic acid content aids in binding heavy metals, stimulating microbial degradation of hydrocarbons, and accelerating soil recovery in contaminated or compacted environments.
In forestry and reclamation, 2.5 K helps restore degraded soils, supports seedling establishment, and improves organic matter and moisture-holding capacity in challenging landscapes. In construction and green infrastructure, it stabilizes soils, reduces erosion, and enhances vegetation performance in applications like bioswales, and rain gardens. Even in environmental restoration projects, 2.5 K provides critical carbon content and microbial stimulation that help rebuild soil biology and support native plant re-establishment.
With its natural origin, rich humic acid profile, and added potassium, 2.5 K delivers a reliable, soil-enriching solution that elevates both product performance and environmental outcomes across an exceptionally broad range of professional uses.

What Our Customers Are Saying
Improved our Fertilizer Products
“We’ve started blending 2.5 K into several of our dry fertilizer lines, and the difference in plant response has been noticeable. It’s improved micronutrient uptake and helped reduce input costs without compromising yield.”
