I'll take this question on the plant breeding side.
You're absolutely right that it's an important component. For good production, you need good soil, you need good management conditions and you also need good genetics. It's a constant balancing act in this particular case.
As an objective for some of the components in breeding, we have researchers working in the area of nutrient use efficiency and people working on water use efficiencies. We know that these components are genetic—they're controlled within the plants—so it's a component of our breeding program, and it's one of many. We also have to have resistance to diseases and to insects, and we have to choose accordingly. That's a component that is already in some of the programs.
What we're probably going to see more and more is increased effort to look at the root systems to try to have plants with bigger root systems. This will help with sourcing water and nutrients, adding carbon to the rhizosphere after harvest and leaving more residue. We'll try to keep that in balance with the portion of energy that goes into the grain that is harvested—
