DiPotassium Phosphate 0-21-26

P-K Source (0-21-26)

High-K phosphate source.

Banded starter P: +5.2% corn where soil-test P is low Source: Quinn et al. 2020, Field Crops Research 254 · Response is P-driven; starter K rarely raises corn yield unless soil-test K is low. Little response on high-P/K soils.

The research

The evidence behind DiPotassium Phosphate 0-21-26, 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).

Agricenter International trial · Memphis, TN
Replicated on-farm trial partnerships across the Southeast: peanut (Auburn University), soybean (Alcorn State University), and forage (Tuskegee University).

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.

NDSU A1851 (Endres, rev. 2022)
Potassium raises yield and stand life mainly below critical soil-test K; on a K-deficient fescue field, K drove roughly half of a +2 ton/ac gain.

Ohio State Extension; University of Kentucky forage-K trial

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.
