An 18-year-old debate over whether farmer cooperatives should be allowed to share crop insurance profits with their members has flared up behind closed doors as negotiators try to finish a new farm bill.

The 2014 farm bill is set to expire in just over one week, raising concerns about disruptions in a number of programs, including one of the largest conservation programs as well as much smaller programs that help commodity groups open overseas markets.

Fires in Oregon wheat fields have claimed thousands of crop acres and taken the life of a farmer seeking to stop a blaze from spreading, and the damage to pocketbooks might not be over yet.

Leaders of the Senate Agriculrure Committee are working this week to protect their farm bill from floor amendments that could cut crop insurance or other key programs.
