Which step is performed after determining the swath width during calibration?

• A. Mark out a 200 ft course
• B. Collect gallons sprayed in the strip
• C. Multiply swath width by 200 ft to determine strip area
• D. Divide the strip area by 43560

Answer: (C)

After you know how wide the spray covers, you need the ground area of the calibration strip to relate how much chemical was used to how large an area was treated. Multiplying the swath width by the length of the calibration course (200 feet) gives the strip area in square feet. That area is the basis for calculating the spray rate, since you’ll compare the gallons sprayed to this area. If you later want acres, you would convert that area by dividing by 43,560 square feet per acre, but the immediate next step is the multiplication to determine the strip area.
