Calibrating your sprayer doesn't have to be complicated! Don't overlook this important step in your habitat management program. In this video, we walk through the why and how of sprayer calibration in 3 easy steps.
What about purchasing a digital speedometer that runs off of GPS and works off your cigarette lighter. Gives a accurate ball park speed and costs around 30 bucks.
You can do this by just filling your tank and spraying a known sized area at a constant speed and noting how much water it took to cover that area. lets say you drive 8 miles per hour and it takes 5 gal of water to cover 0.5 acres. That means it takes 10 gal of water to cover 1 acre at 8mph. Add the appropriate amount of water for the number of acres you need to cover and the appropriate amount of chemicals for that water amount. Lets say your recommended volume of chemicals per acre is 20oz.... So you go to do a 2 acre plot. 40oz of chemical with 20 gal of water (5 gal for 0.5 acres * 4) This will keep people from filling a 25 gallon tank with water and to cover the 2 acres when all you needed was 20. Saves 5 gallons of water and keeps your chemical /water ratio to acres accurate. You can do this right in the field and not have to really remember any equations.
