Huma-K
From $285

AgConcepts — BulkFarmer.com
Potassium humate liquid combining high-analysis humic acids with soluble potassium for dual soil conditioning and fertility benefits.
Huma-K delivers two essential agronomic inputs in a single liquid formulation: premium potassium humate and fully chelated soluble potassium. This unique combination provides the soil-conditioning benefits of humic acid alongside a direct, plant-available potassium source — making it one of the most efficient soil applications available.
The humate fraction in Huma-K improves soil structure and CEC, chelates and mobilizes existing soil nutrients, and feeds beneficial soil biology. The potassium component supports critical plant functions including stomata regulation, enzyme activation, disease resistance, and water use efficiency. When humate and potassium are delivered together, each amplifies the effectiveness of the other.
Huma-K is particularly effective in high-yield production systems where potassium demand is high and soil-applied potash may be limited by tie-up or leaching. It performs exceptionally well in no-till and reduced-till systems where getting nutrients into the root zone without incorporation is a priority.
Applied through in-furrow systems, side-dress equipment, center pivots, or drip irrigation, Huma-K fits any application window and integrates seamlessly into existing programs. Its high carbon content makes it an excellent base for building biological fertility programs over multiple seasons.
Spring pre-plant broadcast
Apply before tillage to work humates and K into the root zone.
In-furrow at planting
Starter-band delivery for immediate potassium and humate availability.
Side-dress with K program
Blend with liquid potassium fertilizer to improve K efficiency.
Consult your agronomist for crop-specific timing. Rates may vary based on soil conditions, crop stage, and application method.
We're not going to overpromise. Here's an honest look at what most farms experience.
K efficiency improves fast
Potassium availability improves rapidly — humate carriers increase K uptake efficiency 15–25% vs. straight K fertilizer. Best ROI on K-deficient or high-pH soils. Run a soil test before starting to confirm baseline need.
CEC benefits kick in
The humic acid fraction starts contributing to better overall nutrient retention — not just potassium. Pairing with Super Hume amplifies CEC benefits and improves the soil's total nutrient-holding capacity.
Documented CEC gains
Farms running full humic programs consistently see 0.8–1.5 meq/100g CEC improvements in 3-year comparisons. Lower synthetic K rates with equivalent or better crop response. The investment pays for itself in reduced fertilizer spend.
Results vary by soil type, climate, baseline soil health, and management. These represent typical outcomes across AgConcepts customer farms.
