What the research shows
Published trial
Estimates only. Costs use delivered list prices at each product's lowest per-gallon size and the rates in our published sample programs; the prebuy discount and your agronomist's rate for your soil test can change them. The yield gain is your number. Results vary with crop, rate, timing, soil, weather and management.
Sized from your soil test
Does your soil actually need Nitro-Maxx+?
Upload your soil test and we'll read every value on it. If your soil calls for Nitro-Maxx+, you get the exact gallons and delivered price. If a different product would earn more first, we'll say that instead.

Straight answer: not Nitro-Maxx+ first
Based on this test, Nitro-Maxx+ isn't where we'd spend your first fertility dollar. Your soil calls for – ahead of it.
When our products don't fit your soil, we say so. The advice is free and the program is built on your numbers, not ours.

The science and the payback
Why it's in your program
The science. The payback.
Science
Backbone N pass across AgriTec's hay (green-up), MI corn (sustained N), and AR cotton (pre-bloom) programs. Slow-release means less leaching, less volatility loss, and tank-mix safety the dry urea programs can't match.
ROI
Replaces dry urea / UAN at lower per-acre cost. Northern hay customers report +5–8% crude protein and +15–25% TDN where N + K timing is maintained. Those are feed-grade quality premiums that compound the cost savings.
What it is
What it is
Slow-Release Liquid Nitrogen (20% N)
6–7× more available than dry urea. Slow-release formulation minimizes burn risk and volatility loss while extending the active period. 2.19 lb of controlled-release nitrogen per gallon, plus 4% calcium, trace minerals and organic matter. The calcium is why Nitro-Maxx+ follows calcium tank-mix rules: keep it out of phosphate tanks.

What it returns
Returns on investment per container.
Pick the size that fits your acres. Every tier is delivered: freight already in the number, no surprises at the dock. The return is what the nitro-maxx+ unlocks on your fields, not what's on the invoice.

Research and trials
The research
The evidence behind Nitro-Maxx+, ours and everyone else's.
Every figure carries its source. Independent research shows where the agronomy holds up; our own replicated trials show it on the ground.
AgriTec trials
-
In a Tuskegee University forage trial, Nitro-Maxx+ produced 3 bales/ac of hay versus 1 bale/ac on the untreated control, roughly a 3× yield response.
Tuskegee University forage trial · AgriTec
-
The full AgriTec wheat program yielded 98.8 bu/ac versus 78.6 on the untreated check, a +25.7% lift on a replicated trial (6 treatments × 4 reps, 24 plots) with identical starting soil (pH 5.4).
Agricenter International trial · Memphis, TN
-
Replicated on-farm trial partnerships across the Southeast: peanut (Auburn University), soybean (Alcorn State University), and forage (Tuskegee University).
AgriTec university trial partners
Independent research
-
Enhanced-efficiency and controlled-release nitrogen averaged +7–8% yield and +13–26% nitrogen-use efficiency versus conventional urea (biggest in high-N, rainfed systems).
Abalos et al. 2014 meta; Zhu et al. 2020 CRU meta
-
Urease-inhibited nitrogen cut ammonia volatilization by ~29–88%.
Liu et al. 2019: Scientific Reports
Independent findings are general to the nutrient or mechanism and describe where a response is likely, not a guarantee on your field. Match them to your soil test; an AgriTec agronomist will help.
