I would like to touch on the question on potash, if I could.
Again anecdotally, last December I was talking to a retailer in Saskatchewan who was getting calls from U.S. fertilizer retailers desperately looking for potash. They were offering to send a truck and buy any potash he had because they were short. Last October, Potash Corporation placed their customers on allocation because of a mine flooding in Russia.
The potash market globally is extremely tight. From what I have been told, I would be simply shocked to find there was the kind of price differences you saw in a survey, that those actually reflect what buying and selling is taking place in the marketplace. That's certainly not the conversations I've had with retailers.
