I can't elaborate on the science, but I can elaborate on the program. As I was saying, we have a greenhouse gas program that addresses that from an agriculture perspective, from a systems perspective. We'll look at livestock systems, at cropping systems, at water-use efficiency, irrigation, etc., as well as agroforestry, the planting of trees in riparian zones and the impact that would have on....
What we'll end up doing through these studies is, as you've mentioned, looking at specific impacts on a nutrient runoff, but also soil erosion. We'll look at algae blooms and the impacts of nitrates on water systems, as well as soil health, all at the same time.
