AgZyme vs. AgriGro: Comparing Biological Fertilizer Programs for Corn and Soybeans

AgZyme vs. AgriGro: Overview

Both AgZyme (from AgConcepts) and AgriGro products are enzyme-based biological fertilizers — making this a more direct product comparison than AgZyme vs. AgroThrive. Both companies use enzymatic and microbial mechanisms to improve nutrient cycling and soil biology. The differences come down to formulation depth, product ecosystem, and pricing.

Company Backgrounds

AgConcepts Inc. is an Iowa-based biological manufacturer that has produced enzyme and humic acid products for over 30 years. Their product line focuses specifically on soil biology and nutrient cycling with AgZyme as the flagship enzyme product.

AgriGro is a Missouri-based company known primarily for its Soil Activator product — a liquid biological that claims to improve soil enzyme activity and nutrient cycling through a microbial-enzyme blend. They also produce FoliarBlend for foliar applications and several turfgrass products.

Side-by-Side Product Comparison

Feature	AgZyme (AgConcepts)	AgriGro Soil Activator
Primary active	Broad-spectrum soil enzymes	Enzymatic solution + microbials
Supporting products	Super Hume, Enhance, Pervaide, Charge, AgCor	FoliarBlend, TurfBiotics, Soil Activator Plus
Typical rate (row crops)	1–2 qt/acre at planting + sidedress	1–1.5 qt/acre at planting
Cost per acre (standard rate)	$12–$18/acre	$15–$22/acre (dealer pricing varies)
Humic acid component	Separate product (Super Hume) — high concentration	Some humate inclusion in Soil Activator
Online purchasing	Yes — BulkFarmer.com (drums and totes)	No direct online ordering; dealer network only
Independent research	University trial data on product pages	Some trial data; primarily dealer testimonials
Tank-mix compatibility	Compatible with UAN, most herbicides	Compatible with most liquid programs

Product Ecosystem Depth

One meaningful advantage of the AgConcepts system is the depth and specificity of the product line. Where AgriGro's core products (Soil Activator, FoliarBlend) cover general biological activation, AgConcepts has developed targeted products for specific soil challenges:

• Super Hume — dedicated high-concentration humic acid for CEC and nutrient retention
• Pervaide — specifically formulated for compaction and infiltration improvement
• Enhance — microbial complexity builder for long-term soil biology
• Charge — starter/in-furrow biological optimized for early root establishment

This modularity allows AgConcepts programs to be tailored to specific soil conditions — you're not using a single product to solve multiple problems.

Pricing Transparency: A Key Advantage of BulkFarmer.com

AgriGro products are sold exclusively through dealers, which means pricing is negotiated regionally and not publicly listed. Depending on your dealer relationship, you might pay $10–$30/acre for a similar biological program — but you can't compare prices without calling multiple distributors.

BulkFarmer.com lists AgZyme, Super Hume, and all AgConcepts products at transparent per-gallon prices with freight calculated to your ZIP code. You see exactly what you're paying per acre before you order.

Which Is Better for Corn and Soybean Operations?

Both products can improve nutrient cycling and soil biology. For a conventional 500–5,000 acre row crop operation, our assessment:

• AgZyme wins on pricing transparency — you know what you're paying and can model ROI precisely
• AgZyme wins on supporting product depth — the full AgConcepts system addresses specific soil challenges better than a general-purpose activator
• AgriGro is a solid product with decades of farmer use — it's not a bad choice, but without online ordering you're dependent on your dealer relationship for pricing and availability

The best approach is to run a split-field trial with whichever product you're currently using and track yield differences over 2–3 seasons. Our breakeven calculator can help you model the economics before you commit.
