About
The USDA Feedstock Carbon Intensity Calculator (USDA FD-CIC) quantifies carbon intensities (CI), in grams of carbon dioxide equivalents per bushel (g CO2e/bu), for four domestic feedstock crops: field corn, soybeans, sorghum, and spring canola. The USDA FD-CIC feedstock CIs reflect the impact of specified regenerative practices used during crop production. The USDA FD-CIC tool allows producers to evaluate nutrient management and one or more of the following practices:
- No-till
- Reduced till
- Cover crops
- Additional nutrient management practices (nitrification inhibitors and manure nitrogen)
The final rule Technical Guidelines for the Production of Regenerative Agricultural Biofuel Feedstocks includes USDA FD-CIC in Subpart C: Quantification of Field-level Crop-specific Carbon Intensity. The rule also defines the practices listed above.
The Tillage Disturbance Index for Soil Carbon (T-DISC) Tool generates a metric of soil disturbance that allows consistent determination of intensity of tillage operations as an input for FD-CIC.
