3-18-18+ pays for itself at 14.9 bu. DAP and potash need 28 to 33.
Corn, soybeans, wheat, and cotton. Placed liquid P and K at the seed, calcium set off your soil math, and a stabilized efficiency layer over the nitrogen you already source. Priced by the acre, delivered free.
Placed liquid against dry DAP and potash
| Metric | AgriTec placed liquid | Dry DAP plus potash |
|---|---|---|
| Break-even to pay for the pass | 14.9 bu corn | 28 to 33 bu corn |
| Placement | In-furrow and 2x2, at the seed on day one | Broadcast, stratified, still dissolving |
| Program anchor | 7 gal/season 3-18-18+, placed plus foliar | Dry DAP plus potash |
The data behind the rec
Corn break-even on the 7 gal-per-season placed-plus-foliar program, against 28 to 33 bu for dry DAP plus potash at 2026 pricing.

Split 2x2x2 nitrogen added 5.2 to 14.9 bu and about $38.22 over a 3-year average, the placement thesis NitroMaxx Plus runs on. Expected range on your ground.
Beck's PFR 2025 Print, split-N study p127-129. Cited trial.
Phosphorus response runs 66.7 percent below 10 ppm Mehlich-3 and 12 to 14 percent above 20 ppm. Placement matters most where soil P is short.

Who this is not for
If your calcium base saturation already tests at or above 75 percent and pH is in range, skip the calcium. We will build the program without it rather than sell you a pass that returns nothing. And if your phosphorus tests above 20 ppm Mehlich-3, the placement gain is smaller. We will tell you that before you buy.

Run your acres through the builder. Snap a photo of each soil test or skip it and we build to the expected range with a free kit in the first order.
In-season timing is the whole game
Sidedress, foliar, and the V5 to V8 window decide the year. Build the in-season passes now so the product is staged for the exact growth stage, not chasing the sprayer.
Run it now, pay after harvest, zero interest for 120 days
John Deere Financial gives 120 days, no payments and no interest, on any order over $1,000 during the program window (through Aug 31). Carry it past 120 days and the rate is Citibank Prime plus 11.5 percent. You need an open John Deere Financial Multi-Use Ag account. We say the carried terms up front so there is no surprise.
