If I were to gaze 20 years into the future, the crops themselves may be the same, but as Stephen is getting at, there will be a lot of different traits within those crops. I think we'll see nitrogen fixation. As we have seen with pulse crops and legumes, where they put nitrogen back into the soil, I think we'll see that coming in the cereal grains. I think 20 years from today we'll be there, so we'll be using less inputs and producing more crop, especially on the fertilizer side.
