We look to science all the time. I'll take the very simplest thing I can think of, which is soil testing. If I don't know what I'm doing, then I'm guessing. When it applies to seed technology and innovations like that, I need the science that backs that up and to trust the science.
On the innovations that you talked about, I think a lot of those things come out of “proven science”, if you like. It's kind of a bad way to put it—“proven science”—but we look to those things and adopt them. I'll go back as far as zero till. That was stuff we did that we recognized had a benefit to us, and we adopted that right away. It was backed up by good science, if you will.
Dave, I don't know if you want to wade in on anything about that.
