Proper sprayer calibration is essential for effective pesticide, herbicide, and fertilizer application. Whether you’re spot spraying a food plot or covering 1,000 acres of farmland, using the wrong nozzle size, spray pressure, or travel speed can result in wasted product, poor coverage, or crop damage.
This tool helps you quickly determine the right operating pressure and ground speed for your sprayer setup.
