Pro Starter+

3-18-18-1 + Yieldmaker + Zinc (Bulk)

Pro Starter with Yieldmaker built in.

Starter P +5.2% corn; +Zn adds 6–7% on Zn-short soils Source: Quinn 2020 Field Crops Res; NDSU Carrington REC (Endres 2023) · P response strongest below critical soil-test P. Zn boost only on low-Zn soils (<0.65 ppm DTPA). Kelp component is a grower-report add.

The +

More than Pro Starter (3-18-18-1 + Zinc)

The + is YieldMaker (kelp) + Zinc.

Starter nutrition plus a kelp-driven regrowth and vigor trigger in one bulk tank, well beyond a planter-box blend.

What it is

3-18-18-1 + Yieldmaker + Zinc (Bulk)

Pro Starter+: 3-18-18-1 with zinc AND Yieldmaker blended in: starter nutrition plus a regrowth/vigor trigger in one bulk tank. Tanker only.

The research

The evidence behind Pro Starter+, 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).

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)
Corn is highly zinc-responsive below ~0.5 ppm DTPA; adding zinc to a starter lifts yield ~6–7% on zinc-short soils and nothing where zinc is already adequate.

U. Minnesota & Kansas State Extension; NDSU Carrington REC (Endres 2023)
A 180-study meta-analysis of seaweed extracts found +17.1% yield on average: mostly horticultural/irrigated, with a smaller, stress-dependent response under row crops.

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.
