Subject: Berry irrigation requirements
Nancy-
The general rule for berries is that they need one inch of water per week.
One inch water on 1 acre = 3630 cubic feet of water/week/acre
3630 cubic feet X 7.48 gallons/cubic foot = 27,152 gal/week/acre
27,152 gal/week/acre = 3879 gal/day/acre = 2.7 gal/minute/acre
But with drip irrigation you wouldn't be watering the whole acre (aisles,
etc.) so you could probably reduce the above amount by at least half,
maybe by 2/3's.
So your per acre water use would be 0.9 to 1.4 gal/minute/acre,
or 1.8 to 2.8 gal/min/2 acres.
Three gallons per minute from the well would do it, assuming that
constant withdrawal at that rate would not deplete the local water table
too much. Of course, you wouldn't need to water when it rains, or in the
off-season.
Anybody feel free to correct the math or concept.
