Super-Hume

AgConceptsHumic Acid

Premium humic acid concentrate derived from leonardite ore — the highest carbon-content humic product available for soil and crop health.

Application Rate:1–2 qt/acre

Product Overview

Super-Hume is AgConcepts' flagship humic acid product, delivering the highest concentration of humic and fulvic acids available in a fully soluble liquid format. Sourced from premium leonardite ore deposits, Super-Hume provides a carbon-rich substrate that transforms soil chemistry, biology, and physical structure simultaneously.

Humic acids are nature's greatest soil conditioner. They chelate nutrients — keeping them available to plants and preventing tie-up — improve cation exchange capacity (CEC), feed and sustain beneficial soil microorganisms, and improve soil aggregation and water retention. Super-Hume does all of this at industry-leading concentration levels.

In crops, Super-Hume stimulates root development, increases chlorophyll synthesis, and enhances the uptake of nitrogen, phosphorus, and micronutrients. Research consistently shows humic acid applications improving yield and reducing fertilizer requirements when applied consistently over multiple seasons.

Super-Hume is ideal as a foundational product in any biological fertility program. It serves as a food source for biological inoculants like Enhance and ZyDrive, extends the effectiveness of foliar applications, and improves the efficiency of every fertilizer dollar spent. Available in 180-gallon pallets through 330-gallon totes for operations of any scale.

When to Apply

1

In-furrow at planting

Delivers humic acids directly to the germinating root for maximum early-season uptake.

2

Fertigation (early vegetative)

Through irrigation systems for uniform coverage in pivots or drip systems.

3

Fall broadcast

Pre-plant fall application for long-term soil structure improvement.

Consult your agronomist for crop-specific timing. Rates may vary based on soil conditions, crop stage, and application method.

What to Actually Expect, Year by Year

We're not going to overpromise. Here's an honest look at what most farms experience.

🌱
Year 1

Nutrient retention improves

Better crop color and less leaching visible in soil tests. Yield response exists but is typically modest (2–4 bu/acre corn) in season one. Humic acids build gradually — persistence matters more than rate.

📈
Year 2

CEC starts climbing

Measurable CEC improvements in soil tests. Crops respond better to the same fertilizer rates — you're holding more nutrients in the root zone. Sandy soils see the biggest early gains; loam and clay soils follow by year 3.

🏆
Year 3+

Structural soil change

Significant CEC improvement across most soil types. Farms successfully reduce fertilizer rates. Water infiltration and aggregate stability are measurably better, with documented results in 3-year soil comparisons.

Results vary by soil type, climate, baseline soil health, and management. These represent typical outcomes across AgConcepts customer farms.

“Soil CEC went up 0.8 meq over 3 years — soil tests don't lie”

I want to give you actual numbers because I got tired of testimonials without data. Before Super Hume: average CEC across my representative fields was 14.2 meq/100g. After three consecutive applications at 1.5 qt/acre pre-plant: 15.0 meq/100g. That's a measurable improvement in my soil's ability to hold nutrients. What does that mean practically? I'm not re-applying potassium as fast. I'm getting better late-season nitrogen retention on my sandy ground. My pre-plant N applic…

“Finally found a humic product that's actually concentrated”

I tried two other humic acid products before Super Hume. Both were so diluted I'd have needed 4 gallons/acre to get meaningful application rates. Super Hume is the first product I've used where the concentration is high enough that 1.5 quarts actually does something. On my dryland wheat in northeast Kansas: year one showed modest response in stand uniformity. Year two I had the best tillering I've seen in this field in 10 years. Year three my protein levels on wheat came in …

“Good product but set realistic expectations for Year 1”

Super Hume is a long-game investment. I didn't see huge numbers in Year 1 — modest 1.5 bu/acre on soybeans. Year 2 was better. Year 3 my tile drainage has improved measurably (better soil structure means better drainage capacity) and my input costs are down. It's not a product that makes your phone ring the morning after application — it's building something real in the soil over multiple seasons. I'd specifically push back on anyone expecting miracles in Year 1. This produc…
