Question

The spray volume recommended for broadcast spraying is 20 gallons per acre (GPA). If you apply the pesticide in a 15-inch band over rows that are 30 inches apart, what would be the actual volume applied on a per acre basis?

a. 15 GPA
b. 20 GPA
c. 10 GPA
d. 40 GPA

Answer 1

The actual volume applied on a per acre basis would be approximately 23,255 GPA.

Step-by-step explanation:

To determine the actual volume applied on a per acre basis, we need to calculate the area covered by the spray. Since the pesticide is applied in a 15-inch band over rows that are 30 inches apart, we can calculate the area of one row and then multiply it by the number of rows per acre.

First, convert the band width to feet: 15 inches = 15/12 = 1.25 feet.

Next, calculate the area of one row: 1.25 feet x 30 inches = 37.5 square feet.

Then, convert the area to acres: 37.5 square feet / 43,560 square feet per acre ≈ 0.00086 acres.

Finally, calculate the actual volume applied on a per acre basis by dividing the recommended spray volume by the area of one row: 20 GPA / 0.00086 acres ≈ 23,255 GPA.
