I think it's absolutely the right thing to do. There's a whole continuum of producers out there. There are some who really haven't done much in the way of soil testing, so you can incentivize them to do soil testing, do a map of their farm and make the right decisions about nitrogen. That's really inexpensive to do. Then there are the farmers who have been more proactive and have done some of these things, and now in order to continue their variable rate 4R practices on their farm, they need to really invest in new machinery, which starts to get into very big dollars, but I think they're also the growers who are showing the industry and other growers the way to go.
I think it's all about having a regulatory environment that's favourable to innovation and incentivizing growers to move in the right direction, because as one of the other witnesses said today, they want to be sustainable, they want to pass on farms to their children in better shape than they got them, and incentives allow them to move in that direction.
