The research

The evidence behind AMS 35%, 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 99 bu/ac versus 79 on the conventional N-only control, a +25% lift on a replicated six-plot trial 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

Corn responded to sulfur in about half of trials (the S-deficient, low-OM and sandy fields), averaging ~+11 bu/ac on responsive sites.

Purdue (26 of 55 trials) + Iowa State (47 sites)
Ammonium sulfate recovered ≥10–17% herbicide control in hard water by tying up antagonistic cations.

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.
