The E15 provision in the Senate Agriculture's proposed farm bill differs from the House legislation in how it would handle SRE changes. Ag groups such as the American Farm Bureau Federation say they are strongly in favor of the voluntary E15 measure and broader Senate farm bill. Outside of E15 and SNAP additions, the farm bill draft is broadly similar to the version unveiled in late June. Senate Agriculture Committee Chairman John Boozman, R-Ark., will lead a markup of the proposed legislation on Thursday. We’ve lost 200,000 farms in a decade, and a modernized farm bill will help stabilize the struggling farm economy.
