the tape really is that long
On drip tape we don't talk gallon per minute we talk gallons per hour.
this drip tape has one gallon per hour emitters every 6 inches. so to take 700 gallons per minute, so you have 7000 emitters dragging behind the pivot. So the farther you get out the more emitter you have to have to get all the water. the last tower of the pivot, the drip tape is over 80ft long and it is on the ground. what you see coming off the pivot are feeder hoses, that range from 15ft to 25ft, they the drip tape is attached.
For cutting hay and barley around here, they guys cut into the center of the pivot and then move the pivot into the center. then they send a guy down the pivot to pull all the drip tape under the pivot. When harvest is over they start up the pivot and the tape will straighten out.
For winter, on farmer just leaves it alone and the wind will blow it around, The Barley field in the picture has been planted to a cover crop, those farmers are going to graze it off. so they are planning on taking the tape and zip tying 10- 20 strands in several different place so it will look like a pony tail, then they are going to hang the tape on the pivot to keep it away from the cows, it will be interesting to see.
one thing we have learned is that we can sprout Seeds with SDI, you just have to have a closer spacing, 30-36in apart, at that spacing we can move enough water to the surface to start your corn, wheat, barley, beans and sugar beets. but Alfalfa will still need a surface application. I do need to clarify, I have not seen any SDI in sandy soils, so I do not know how it would work. but as usual this all depends on you what kind of soil you have for SDI.
sorry for the long response. I am liking Drip the more I am around it.
