I'm not sure why Canada is the second highest in the world. Japan is the only country in front of us. Where I farm in Saskatchewan, we have huge potash mines, so it's a little mind-boggling.
That's not something that we get to change. If we want to grow the best crop that we can, the only things we are able to control in growing that crop to its full potential are our inputs and the way we take care of that seed.
