Pro Starter with YieldMaker built in.
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 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)
-
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.
