1 acre = 43,560 sq ft

1" of water per acre = 27,154 gallons

Figure out your patch size.
My patch for Example:
26ftx42ft=1092 sq ft

1092/43560 = .025 acres

.025 x 27,154 gallons = 678.5 gallons

678.5/7 = 96.9

So to apply 1 inch of water per week to my patch takes 97 gallons a day. BUT you should use this as a STARTING point, if you soil doesn't drain well 1 inch a week could be too much, if it drains too well 1 inch might not be enough. My grandfather taught me to dig down 6 inches, grab a handful and squeeze it. If it won't make a ball it is too dry, if it makes a ball and you can't easily rubb it between your fingers and break it up completely, it's too wet. Adjust watering accordingly.

123,
To put 1 inch of rain on your patch you need 66 gallons per day.

743/43560 = .017 acres

.017 x 27154 = 462
462/7 = 66 gallons per day

The sprinkler should have a FLOW rating. This is how many gallons per hour it will deliver. There are many different types of heads that deliver a wide range of FLOW, so you need to know this figure for your sprinkler. Or you can buy an inline meter (fromn $75 to $750 -- look for water flow meter in google search) and measure the ammount you are actually delivering.

Multiply number of heads by FLOW to get how many gallons per hour they will deliver. Dividing 66 by that number will tell you how long to run the sprinklers.

Example:
Your heads deliver 10 gallons per hour and you have 15 heads

10x15 = 150
66/150=.44
.44x60 minutes = 26

So 15 heads delivering 10 gallons per hour will deliver the needed 66 gallons in 26 minutes.


LUKE, thanks.

Another way to do it on smaller area's.Is to take square ft x 144 to get cubic inches, divide by 231( amount of cubic inches in 1 gallon), then to divide by 7 (days in aweek)to acheive daily amount..same ending diferrent means to get there

a lot of your watering needs depends on how well your patch drains.
an inch of water in one patch could be perfect while an inch of water in another takes much longer to drain through the soil.in some soils one inch is like a fart in the wind.

for this reason we growers should always test our patch for proper drainage. plus a good old fashioned ball of soil compressed in the palm of your hand can also tell you a lot.

he is right, and I learned this a few years ago off Quinn, his patch drained twice as fast as mine did, so I really had to adjust my water according to what Quinn was using by a huge amount.
For example, my patch would still look wet 24 to 48 hrs after watering while Quinn's would be bone desert dry the very next day. He told me his patch drains at a really fast rate.

Just to add this, I then had to change the way I was watering again after I installed just 3 french drains down 2 outside edges and 1 down the center of my patch , the difference in drainage was huge, it really helps alot in areas that water wants to flow and then lay naturally after a really hard and long rain, I also think by installing these french drains it will also help me in soil disease problems somewhat.

Thanks for them figures Cntyboy
