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

Orthophosphate NPK Liquid + Foliar

Balanced ratio engineered for corn, wheat, hay, and pasture. Slow-release nitrogen, seed-safe, applied any stage of growth.

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.
