(NAFB.com) – The USDA announced the publication of an interim rule on Technical Guidelines for Climate-Smart Agriculture Crops Used as Biofuel Feedstocks. It establishes guidelines for quantifying, reporting, and verifying the greenhouse gas emissions associated with the production of biofuel feedstock commodity crops grown in the U.S. The rule covers three feedstocks, including soy, corn, and sorghum. It also covers climate-smart practices that could reduce GHG emissions or sequester carbon, including reduced till and no-till, cover cropping, and nutrient management practices like using nitrification inhibitors. The interim rule also allows for the adoption of CSA practices both individually and in combination. This means farmers would have the flexibility to adopt the CSA practices that make sense for their operation while still being able to produce feedstocks with reduced carbon intensities under the rule. USDA is requesting public comment on the interim rule to help inform future revisions or additions. Go to regulations.gov.
