Guaranteed analysis
3-18-18 liquid ortho and poly P plus K, plus the YieldMaker micro pack.
What it does
Low-salt, ortho-dominant phosphorus and potassium placed in the furrow or 2x2 is available to the seedling root immediately, when dry DAP and potash are still dissolving and stratified. The YieldMaker pack rides along with zinc, manganese, boron, and a kelp biostimulant. The same liquid runs as a V5 to V8 foliar dribble.
What it will not do
Placement, not rate, is the point
Seven gallons of placed liquid does the work of two to three times the phosphate in dry form because it is where the root is on day one. We are selling placement efficiency, not more pounds.
Trial data and expected range
The 7 gal-per-season placed-plus-foliar program breaks even at 14.9 bu of corn, against 28 to 33 bu for dry DAP plus potash.

Tank-mix and handling
RED: never tank-mix 3-18-18+ with Pro-Cal or Advanced-Cal. Calcium plus high-salt phosphate forms a jelly. Keep them on separate passes. In-furrow carrier 4 to 6 GPA, clean screens, strong agitation.
3-18-18+ usually ships inside the corn program anchor. Build the whole program off your soil test and see it in context.
