SPRAY IT CALCULATOR

US Gallons per Acre is the unit of measure for “application rate” common in the United States and some areas of Canada and Mexico. Liters per Hectare is the unit of measure for “application rate” common in most of the world where the metric system is used.

The distance between nozzles on a broadcast spray boom.

The forward speed of the spraying equipment. Speed sensors should be calibrated or checked for accuracy regularly. Speed can be checked by timing how long it takes to travel a measured distance: MPH = feet x 0.682 ÷ seconds or Km/h = meters x 3.6 ÷ seconds

The volume of finished spray applied per treated area (US: US Gallons per acre, metric: Liters per Hectare). Follow the instructions on the pesticide label to determine an appropriate spray application rate. If a range of application rates are listed, use the rate that matches your situation or consult an agronomist.

The weight (US) or mass (metric) of the spray solution per unit volume (US: lbs/gal, metric: kg/L). High density liquids like some fertilizers pass through nozzle orifices more difficultly than plain water and low density liquids. Solution density must be considered and accounted for in calculations to select a spray nozzle and spraying pressure.

The size and variation of droplets produced by a spray nozzle. This is a critical performance characteristic for selecting a spray nozzle that is suited to a particular application. The classification system used In this calculator is the American Society of Agricultural and Biological Engineers (ASABE) S572.1 standard. It defines droplet classification categories from Ultra Fine to Ultra Course. Smaller droplets provide more coverage, but are prone to drift, while larger droplet sizes control drift, but may not provide adequate coverage.

The number of nozzles directed on a single sprayed band.

The width of the sprayed zone in a banding application.

A number related to the flow rate of a spray nozzle. These numbers relate to the nominal flow of a spray nozzle. Common sizes are 01, 015, 02, 025, 03, 035, 04, 05, 06, and 08. For example, size 02 nozzles will flow US: 0.2 US GPM at 40 psi, metric: 0.8 L/min at 3 bar.
