I don't think farmers trust anything. I think they have to test it.
My dad was always that way. He would say, “This looks great. I'm going to do some alternating strips, and I'm going to prove it on my farm.” However, you need that data first to get them to buy into the test because the test is a risk for them. They're putting money on the table to do the test, so they want to see the proof. They want to try it on their farm, but once they're in, then the next year they're in 100%. I saw that with many things on our farm.
I remember trying to make sure the cultivators stayed in the rows. As soon as my dad figured out that the computer could do it better than I could, we had it on every tractor.
