Between 1985 and 2000. So when the markets are soft the price does go down.
What we've seen since 2000 is that 40% of the production capacity of the U.S. nitrogen fertilizer industry was permanently closed because of high natural gas costs and the fact that those plants were not able to compete globally. The price of fertilizer was relatively flat around the world. Those plants closed and that production was lost to us.
I do remember coming before the committee and members of Parliament to say that we were very concerned about the cost of natural gas, which is a primary feedstock raw material for nitrogen fertilizers, and about the ability of our industry to compete and succeed in the future, given the high natural gas costs in North America compared with the rest of the world.
So the U.S. plants close, demand starts to go up, and you have this very tight supply-demand situation. I understand that farmers are not happy with the fact that prices have probably doubled in the last couple of years. It is a significant price increase.
