Formula
Product per tank = (tank volume ÷ spray volume per ha) × product rate= 4

Simplified agronomic model: results use the rates, grades and coefficients you enter and ignore soil type, weather, variety and local regulations. Confirm with a soil test, the product label and an agronomist before applying anything.

What does a tank mix calculation actually solve for?+
It converts a label rate — typically expressed per hectare or per 100 liters of water — into the actual quantity of product to add to your specific tank size, given your target spray volume per hectare. It answers 'how much product goes in this tank,' not just what the label rate is.
Why does the same label rate require a different amount of product depending on my sprayer?+
The label rate is fixed per hectare, but how much area one tank covers depends on your sprayer's tank size and your chosen water volume per hectare. A smaller tank or a higher water volume per hectare means each tankful covers less area, changing how much product goes into that specific tank.
What happens if I get the water volume per hectare wrong?+
The product rate is only correct for the water volume you actually apply — if you spray at a different water volume than assumed, the concentration in the tank no longer matches the intended per-hectare dose, potentially under- or over-applying the active ingredient.
In what order should I add multiple products to the tank?+
As a general rule, follow the mixing order on the label or the standard sequence (wettable powders and dry flowables first, then suspension concentrates, then emulsifiable concentrates, then surfactants), agitating between each addition. Mixing out of order is a common cause of tank clogging or product separation, independent of the quantities calculated.
Should I mix the exact calculated amount or add a safety margin?+
Mix only what you need for the area to be sprayed, since unused tank mix is typically hazardous waste that must be disposed of according to label instructions, not simply dumped. Calculate carefully rather than over-mixing 'to be safe.'
