AgriTec 3-18-18 Performance Series

One 3-18-18.
Built four ways.

Same analysis in every jug. What changes is what rides along with it: nothing, the root zone, plant uptake, or both.

The starting point

Smaller than bulk? Package prices

Freight is already inside these. Per gallon they run above the bulk figure, which is what the 2,000-gallon minimum buys you.

Order it

Totes & drums, shipped with freight included

Packaged prices run higher per gallon than the bulk figure above: they include the container and the freight to your door. The $5.50/gal bulk price starts at 2,000 gallons, before delivery.

The second option is cheaper than the first. One package adds $1.50 a gallon. Going on to take both adds $2.50, so the second one only costs $1.00. Whichever package you were leaning toward, the other one is the least expensive thing on this page.

Same field. Different equipment.

You already know this difference. You have felt it in the seat.

Better equipment is not the same as finished. A newer machine still buries itself if it hasn't got what it takes to pull out. Starter fertility works the same way, the analysis gets you into the field, the packages are what get you through it.

The starter itself Root zone Plant uptake

The same analysis, carrying what it takes to keep moving, in the root zone and into the crop.

Ensure the nutrients you pay for are seen in the combine.

A campaign line, not a yield guarantee. Results vary with crop, rate, timing, placement, soil, weather, and management.

The evidence

Why any of this is worth the extra dollar.

Here's the independent work behind starter phosphate and zinc, what growers running it have said, and the labels, so you can check the claim rather than take it.

On the starter phosphate

+5.2% corn from banded starter P

Source: Quinn, Lee & Poffenbarger 2020: Field Crops Research 254, 474 US comparisons

Where it doesn't apply: Average across US trials; strongest below critical soil-test P and fades on high-P soils (74% of trials responded). Not a guarantee.

On the zinc

Starter P +5.2% corn; +Zn adds 6–7% on Zn-short soils

Source: Quinn 2020 Field Crops Res; NDSU Carrington REC (Endres 2023)

Where it doesn't apply: P response strongest below critical soil-test P. Zn boost only where soil Zn is low (<0.65 ppm DTPA); none where Zn is adequate.

These are independent findings about the nutrients and placement this product uses, not trials of AgriTec's finished blends. They describe where a response is likely, not what your field will do.

What growers said

Verbatim, from 9 states. Field experience, not a controlled trial.

IN · 2023

"We used the 3-18-18+ on our beans and saw a significant yield increase. I want to use that again on my beans and run some hay and pasture ground with y'all as well"
