Will 5,000 gallon/month sea be adequate for 3,000 square foot St. Augstine pasture surrounded by Florida?
Answers: The 5,000 gallons is probably more like a weekly watering ration.
A typical watering schedules more or less 1" per week in hot dry weather so, 4 weeks x 4" (1" per week) x 3,000 square feet = 2700 cubic foot or about 20,000 gallons per month.
