drip irrigation info request
Posted by mike on 8/24/2007, 1:36 pm
I have about an acre of vegetables, tomatos, eggplant, peppers, squash, zuchinni and cucumbers, all grown under 3 foot wide fabric. I have no irrigation and need to set some up. I would like to use drip tape under the fabric. I have a dug well i can pump out of about 200 feet from the fields. Slope is not an issue as it is relatively flat. my rows are under 100 foot in length and i would like to zone the system so that there would be approximately 500 feet of drip tape per zone. i will likely start with a manual system. i am Rhode Island and have a very loamy soil with good water holding capicity. i have a shallow well pump an am wondering if it will be adequate to use. i am assuming that i need to maintain 10 to 15 psi out of it to the mainfold ? the dug well i have i am un certain of the volume i can pull over a lenght of time. So i am planning to start by figuring my zones at 500 feet of 8 mil 5/8 tape with .22 emitters at 12 inch spacing and run for 1 hour each zone to limit withdrawl to the 120 gallons (or so) per zone and run at different times to allow for recharge in the well. This will, if it works correctly, allow me to water each zone at least 2 to three times per week and still simulate a 1 inch rainfall. although a little crude it will at least let me be more consistent than depending on rainfall alone. any ideas or insight you may have would be helpful. I also need to know what materials i would need to go from the 1 inch plastic supply line to the drip tape zones and your pricing. If you need more info please let me know and i wil gladly discuss.
tomatos are single row per 3 foot wide fabric rows.peppers, eggplant, and the curbits are double row per 3 foot wide fabric rows. for the double row do i need to run 1 or 2 lines of drip tape?
