Which Exactrix System is best for my Anhydrous Ammonia application needs?
Your needs are simply based on flow of NH3 in one minute of time. You must determine your maximum NH3 flow rate. If you are a VR-N candidate make sure you consider your maximum flow rate at highest ground speed. Most producers allow for a 25% design margin above maximum anticipated flow. This allows for low tank pressure in cold weather, rolling ground and low tank elevation. Calculate gallons per minute flow by multiplying acres per minute Xs gallons of NH3 per acre. Remember 4.21 lbs. of N is in each gallon of agricultural grade NH3. Example, 200 lbs of N per acre is 47.50 gallons NH3 per acre. A 40-foot applicator will cover .808 acres at 10 mph. .808 acres per min. Xs 47.50 gallons per acre = 38.38 gallons per minute. Always multiply your top rate and speed for gallons per minute at 38.38 gpm Xs a 1.25 design margin = 47.98 gallons per minute. Note: A 5 mph application will be .5 of 48 gallons per minute with design margin or 24 gallons per minute with a 1.25 design margin. A 60-fo
