I can talk a little about that, yes.
We've become more moisture efficient. I think it is one of the big things in some of the drier areas of western Canada. We will switch to no till, which conserves more moisture and that increases yields. We started using more fertilizer and better seeding techniques, with more precise seeding more precise fertilizer placement. We just have more knowledge, and yes, more technology.
I think it has really increased our production. For example, we used to think that 50 to 55 bushels of wheat per acre was a really good crop. Now in some years we've produced almost double that, so it's been huge, and that is part of the challenge when we're talking about rail movement and some of these other things too.
