Spray Tank Dilution Calculator
Use field area, carrier volume, tank capacity and label rate to estimate hectares per tank, product per full tank and total product.
Calculate spray product per tank
Use field area, carrier volume, tank capacity and label rate to estimate hectares per tank, product per full tank and total product.
How the spray tank dilution calculator works
Area covered by a full tank equals tank capacity divided by spray volume per hectare. Multiplying that area by the product label rate gives product per full tank. Total product is simply field area multiplied by the per-hectare product rate.
When to use this farm calculation
This calculation helps translate a label rate per hectare into a practical tank mix after the sprayer has been calibrated to a known carrier volume. It also makes the final partial load easier to plan.
Inputs, units and assumptions
The tool does not determine whether a pesticide, fertilizer or adjuvant rate is permitted. Use only the approved label rate, required personal protective equipment, compatibility instructions and local regulations. Calibrate actual nozzle output before relying on the tank plan.
Practical example
At 200 L/ha with a 600 L tank, a full tank covers 3 ha. A 1.5 L/ha product rate therefore requires 4.5 L of product in each full tank.
