What Biological Inputs Actually Do to Your Soil
On the left: compacted, biology-depleted soil with limited root access and poor nutrient cycling. On the right: the same soil profile after 2 seasons of biological inputs — dense root networks, active microbial communities, and dramatically improved structure.
Root depth increases 30–60% in biological program fields
Soil microbial biomass up 22–38% after 2 seasons
CEC improvement of 0.8 meq/100g average in university trials
Featured Products
AgConcepts most popular biological inputs in bulk pricing.
AgZyme
Microbial Enzyme Activator
Speeds up nature's process of turning dead crop residue into available nutrients.
Accelerates organic matter breakdown and releases locked nutrients. A cornerstone biological for row crops and vegetables.
Super Hume
Concentrated Humic & Fulvic Acid
Acts like a sponge — binds nutrients to soil so rain can't wash them away, then slowly feeds your crop.
12% humic acid derived from leonardite. Improves cation exchange, soil structure, and nutrient uptake in all soil types.
Charge
Biological Soil Stimulant
Adds billions of beneficial microbes and fungi that wake up your soil's natural productivity.
Proprietary blend of beneficial bacteria, mycorrhizae, and carbon compounds. Activates native soil biology fast.
AgCor
Foliar Micronutrient Complex
Chelated micronutrients sprayed on leaves — absorbed in hours, not weeks.
Chelated micronutrients with biological carriers for rapid foliar uptake. Works across all major crops and application windows.

The Recommended Starter Combination
Not sure where to begin? Over 80% of farms new to biological programs start with this combination — and it works because AgZyme and Super Hume solve the two biggest problems in depleted soils together.
AgZyme — The Activator
Breaks down crop residue and releases locked nutrients. Your soil starts cycling nitrogen and phosphorus more efficiently within weeks.
Super Hume — The Holder
Humic acid binds those newly released nutrients to your soil so rain doesn't wash them away. Together with AgZyme, you unlock and then hold nutrients.
What to Expect, Season by Season
Season 1
Faster residue breakdown, improved soil aeration, visible crop response to released nutrients.
Season 2
Measurable increase in soil organic matter. Most farms reduce synthetic N by 15–25% without yield loss.
Season 3+
Self-sustaining soil biology. Lower input costs, higher organic matter, reduced compaction.
Plain-English Guide
New to Biological Farming? Here's What These Terms Actually Mean.
No agronomist jargon. Just simple explanations for the concepts you'll see on product pages.
Biological / Microbial Inoculant
Adding helpful microbes to your soil — like giving it probiotics. They break down nutrients and make them available to your crop roots.
Enzyme Activator
Speeds up nature's process of turning dead crop residue into next year's soil nutrients. Think of it as turbocharging your decomposition cycle.
Humic & Fulvic Acid
Natural soil compounds that act like a nutrient sponge — hold nutrients in your root zone so rain can't wash them away, then slowly release them to your plants.
Leonardite
Ancient compressed plant matter (similar to soft coal) that's naturally packed with humic acids. The highest-quality raw source for humic products.
Mycorrhizae
Beneficial root fungi that extend your plant's root system by up to 100x, reaching water and nutrients that roots can't access on their own.
CEC (Cation Exchange Capacity)
How well your soil holds onto nutrients instead of letting them leach away with rain. Higher CEC = more nutrients available when your crop needs them.
From the Field
What Farmers Are Saying
“We cut our synthetic nitrogen rate by 35% and still beat our five-year yield average on corn. The soil is noticeably different — better structure, better water retention. We're not going back.”
Jake Thornton
Thornton Family Farms — Central Iowa
2,400 acres corn/soy
“I was skeptical at first. But after the dry spell in August, my fields treated with Charge held moisture way better than my untreated fields. Paid for itself that one summer.”
Maria Reyes
Reyes Organic Farm — Fresno, California
340 acres tomatoes/peppers
“Three seasons of AgZyme and my organic matter went from 1.1% to 2.3%. My agronomist didn't believe it until he saw the soil tests. These products work.”
David Reinhardt
Reinhardt Grain — Southern Illinois
1,800 acres row crops
If It Doesn't Pay for Itself by Year 2, We'll Make It Right.
We're not going to promise you a 10x return in year one — that's not how soil biology works. What we will promise: if you run a full program for two seasons and don't see a measurable return in yield, reduced inputs, or soil health, contact us. We'll redesign your program at no charge and work with you until it does.

The Biological Revolution
Why Farms Are Switching from Synthetic to Biological Inputs
After decades of synthetic nitrogen, phosphorus, and potassium applications, soil biology across the Midwest and beyond is depleted. Yields have plateaued. Input costs have climbed. And farmers are discovering that the answer was underground the whole time.
Biological inputs — microbial inoculants, enzyme activators, humic acids, and biological catalysts — work with your soil biology instead of replacing it. They release locked nutrients, improve water retention, reduce compaction, and cut the synthetic inputs you need to apply.
AgConcepts has spent decades perfecting biological formulas that work in real field conditions. BulkFarmer.com makes those products available at bulk pricing, drop-shipped to farms that need them.

Common Questions
Frequently Asked Questions
QWill biologicals work with my current fertilizer program?
Yes — all AgConcepts products are designed to complement your existing program, not replace it overnight. Most farms add biologicals alongside their current inputs first, then reduce synthetics as soil health improves. Start with AgZyme or Super Hume alongside your normal N-P-K program and measure the results.
QHow long until I see results?
Foliar products like AgCor show results within days (visible crop response). Soil biologicals like AgZyme and Charge typically show measurable improvement within 4–8 weeks of application. The biggest gains — improved organic matter, reduced synthetic input needs — build over 2–3 seasons as your soil biology establishes.
QDo I need special equipment to apply these?
No. All products are liquid concentrates that go through standard sprayers, fertigation systems, or irrigation lines. They're compatible with most liquid fertilizer tanks and injection systems. No special equipment required.
QWhat's the minimum order quantity?
There is no minimum. You can order a single 5-gallon jug to try a product before committing to drums or totes. Free shipping applies to orders over $500. For tote quantities (275-gal+), freight is quoted per order based on your location.
QAre these products approved for organic operations?
Several AgConcepts products are OMRI-listed and approved for certified organic use. Product detail pages indicate organic approval status. If you have a specific certification question, contact us and we'll confirm compatibility with your certifying body.
QHow do I know which product to start with?
For most farms, start with AgZyme (enzyme activator) paired with Super Hume (humic acid). This combination addresses the two biggest limiting factors in depleted soils: slow nutrient cycling and poor nutrient retention. It's the most common starting point for farms new to biological programs.
