Certainly, and David probably has some comments on this as well. We're talking about increasing the volume of yield from our crops, but we're also talking about using more of the total crop we have available.
For instance, right now in ethanol production we're only using the starch component of that seed. Plant breeding companies and biotechnology companies are looking at how we can use more of that seed for ethanol production, so instead of only using 75% of the seed, we're using 80% of that seed. Then we're looking at how we can use some of that leftover cornstalk for these other industrial purposes, how we can take that cornstalk, turn it into simple sugars, and then refine that into our carpets and our clothing.
So we're talking about getting more value, more yield, more product per acre, and part of that is what Performance Plants is doing in terms of increasing the overall biomass, increasing the productivity of those acres. But part of it is also using the total available plant more completely.
