Work out spray volume per acre instantly with clear inputs, formula shown and shareable results.
Application volume is the standard sprayer calibration identity: L/ha = total nozzle output (L/min) x 600 / (swath width in metres x speed in km/h). The factor 600 converts minutes and kilometres into hectares. Getting this right matters more than the tank mix, because volume error translates directly into dose error.
Sprayer calibration
L/ha = flow (L/min) x 600 / (swath width (m) x speed (km/h))
Acre basis
L/acre = L/ha x 0.4047
Pesticide application rates are legally binding label conditions. Verify calibration by physical measurement before spraying and observe buffer zones and re-entry intervals.
Spray a measured area with a known tank volume and compare. Or catch output from each nozzle for one minute — replace any nozzle more than 10% off the average, as worn tips over-apply.
No. Faster travel cuts the volume applied per hectare but the product concentration in the tank is unchanged, so the dose per hectare drops and control fails. Re-calibrate the mix if the speed changes.
