How it's calculated

Acres per tank = tank size ÷ spray volume (gal/ac). Product per full tank = rate per acre × acres per tank. Total product = rate per acre × total acres. For a % v/v adjuvant, gallons per tank = tank size × % ÷ 100.

Fill the last (partial) tank to the leftover acres, not a full load, so you don't over-apply on the final pass.

Row Wise gives you spray windows for every field — wind, Delta-T and inversion risk — plus tidy spray records you can hand to an auditor.

Frequently asked questions

How do I calculate how much product to put in each tank?

Divide your tank size by the spray volume per acre to get acres per tank, then multiply that by the label rate per acre. That's the amount of each product for a full tank.

How many tank loads will I need?

Divide total acres by acres per tank. Round down for full tanks and mix the remainder for the final partial load so the last pass isn't over-concentrated.

Can I mix multiple products?

Yes — add up to three products with their own rates and units. Always follow the label's mixing order and jar-test compatibility for unfamiliar combinations.
