Top House and Senate negotiators plan to meet again Wednesday behind closed doors to try to reach agreement on a new Farm Bill as a Jan. 1 deadline fast approaches.

The talks come while the Senate remains in recess, but Sens. Debbie Stabenow (D-Mich.) and Thad Cochran (R-Miss.), who lead the Senate Agriculture Committee, agreed to return to Washington early to continue the negotiations in hopes that a bill might be ready as early as next week.

There is agreement over vast portions of the omnibus measure — including plans to end billions of dollars in direct payments to farmers — but significant differences remain in several key areas regarding new safety nets for commodities and funding for the Supplemental Nutrition Assistance Program, more commonly known as food stamps.
