Agriculture experts from around the world gathered in St. Paul to talk about the future of farming. The University of Minnesota conference comes at a time when farmers are facing unprecedented pressures resulting from plunging prices, rapidly changing technologies, and increasingly stiff competition in world grain markets. The challenge For US policy makers is equally tough, for taking care of farmers at home may clash with equally important objectives -- one of these is inducing Foreign countries to open their markets more fully to American agricultural exports. ANOTHER is get them to end or lower subsidies for their own farmers that may crowd American farmers out of other export markets.
