I get the impression the House will likely oppose the conservation compliance requirement for crop insurance and the payment limitation, and since there's weak support on Senate Ag, if it goes to conference it will be out. I also get the impression the House may retain a bit more of the current structure (i.e. counter-cyclical programs, etc.) than did the Senate.
I'm always impressed by Farm Policy's completeness and Sustainable Agriculture's good analysis (even though I don't always agree with their policy positions, they seem to know their stuff).
