First of all, Clyde and I are not involved in the marketplace, so I can't tell you exactly what the different prices are at any particular time. Mr. Haney might be able to answer that more specifically.
But I did talk to some manufacturers and distributors last spring regarding the KAP study, and I asked whether it reflected the market conditions. The answer we got back from both a distributor and a manufacturer was that it did not reflect their perception of the marketplace during the last spring season.
If you look at the dealer report from Green Markets that I included in the package we sent to you, it identifies the prices of different fertilizer materials at the wholesale level. For example, in the northern plains, urea is between $568 and $579 U.S.; in western Canada it's between $575 and $600 Canadian. The prices are basically the same, so if the wholesale market is the same, why wouldn't the retail market be the same?
Those studies seem to be inconsistent with what you would logically assess and conclude from the marketplace. It's an open border, and both farmers and retailers can move urea back and forth and purchase it from the least expensive source. If there is a minor difference in the market, it will equalize very quickly in a short period of time. So it's inconsistent with how we understand the market to work.
