In application rate calculations, GPA stands for which of the following?

• A. Gallons Per Acre
• B. Grams Per Acre
• C. Growth Per Acre
• D. Grains Per Acre

Answer: (A)

In application rate calculations, you describe how much liquid is being applied over a specific area, so the common measure is volume per area. Gallons per acre is the standard way to express that, which is exactly what GPA stands for. So, applying 8 gallons to one acre means a rate of 8 gallons per acre. If you see a rate like 0.5 gallon per 1,000 square feet, you can convert it to gallons per acre by multiplying by 43.56 (since one acre equals 43,560 square feet), giving about 21.8 gallons per acre. The other options aren’t typical units for describing liquid application rates in turf, since they don’t represent volume per area.
