The farm bill, a massive Gordian knot of legislation that rolls through Congress every five years or so, has rolled into Congress. Not recently, mind you, it's already been under discussion and in negotiation for a year. The bill touches nearly every aspect of America's food system -- and sucks in more than a few tangential issues as well. (If you're new to the bill and its details, our page of posts on the topic is the best place to start. NPR also has a good overview.)
Right now, the Senate is considering the Agriculture Reform, Food and Jobs Act of 2012 (read: the farm bill, though ARFJA is also catchy). It left the Senate Agriculture committee and arrived on the Senate floor, where it was promptly peppered with over 90 amendments.
We went through and identified five of the 90 that are most worth paying attention to. If you have additions or questions, feel free to leave them in the comments; consider this a living document. As the bill progresses through the Senate and then the House -- perhaps even before the existing legislation expires at the end of September -- we'll track its evolution and likely impacts.
