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.

The science and the payback

Why it's in your program

The science. The payback.

Science

Slow-release N, balanced for the same crop families (corn / wheat / hay / pasture) AgriTec runs across, seed-safe at any growth stage. The all-purpose backbone when one SKU has to fit multiple crops on the same farm.

ROI

One product for mixed operations = lower inventory carry + fewer half-tanks left at year-end. Versatile across corn → wheat → hay rotations without re-tooling the tank.

What it is

Research and trials

The research

The evidence behind 9-18-9, 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

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).

Independent research

Banded starter phosphorus raised corn yield +5.2% on average across 474 U.S. comparisons, strongest below critical soil-test P, fading on high-P soils.

Quinn, Lee & Poffenbarger 2020: Field Crops Research 254
Banded 10-34-0 added +5–7 bu/ac corn on low-to-medium-P soils across 8 site-years.

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.
