How many gallons does it take to spray 1 acre?
A 1-acre land will require one of the smaller units on the market. A gallon of mixed solution can cover up to 1000 square feet of land. So, to spray an entire acre of land, you will require about 44 gallons. However, these figures may vary depending on the type of solution and amount sprayed per minute. It may also vary depending on herbicide instructions.
