Wow. Interesting information.Technically, to be classified as a "real farm" requires that I operate a full-time farm and not just a part-time (hobby) farm. To be qualified as a full-time farm requires that more than 50% of my annual income comes from my farming operation and I'm nowhere near that.
Irrigation systems are very expensive. A single rotary system like what I think you're describing would cost over $40,000.00 to cover a 40 acre area. My ground is broken up into four 5-acre pieces, one 8-acre piece, one 27-acre piece, and one 3-acre piece. To irrigate those would require a separate system for each. Fortunately for me our average year is more likely too wet rather than too dry so irrigation is not required on my soil.
The opposite option would be to put in drain tile on some of the wetter pieces of ground to help the soil dry out in the spring. I would never use a drain tile to drain a wetland for farming or to pattern tile an entire field because I don't agree with doing those things but those places that I had to work around this year would be a good place for a few single drain tiles so that I could more consistently farm those pieces. But, installed drain tile too can be very expensive. I've heard as much as $2-$3 per foot of tile. All I would gain with that is that I'd not have to skip around those 4-5 acres in 2 out of 5 years when things are a little too wet. Again, it would take many years to pay for the tile.
Why would you never use a drain tile?
And what is it!
