"They can look at the field and see why it looks different. An example of that is we had soybeans earlier. I noticed that in the following crop of corn, it wasn't even. It was kind of up and down. Some of it was a little taller. But, I noticed all of it [the taller corn] was every six rows. Well, that told us something, but I didn't know what It was just a slight wave in the corn every six rows. it had a pattern. It's kind of a mystery, you know. It's an unsolved mystery It had been in beans the year before, and the combine left more of the trash every six rows as we went. And that conserved enough moisture so that you could see it in the crop growth the following year. I thought that was rather interesting. And also more people are experiencing that, residue on the surface preserved moisture. And it's going to be a slow process but it's coming into its own. You can see it if you don't believe it. If you see it you'll believe it."
