This research analyzes national and regional adoption of no-till and strip-till planting systems; cover-crop use; and nitrogen-fertilizer application rates, timing, and methods. Results show that U.S. farmers' adoption of these practices varies widely by crop and region. In addition many farmers are "partial" adopters, adopting these conservation practices on some but not all acres of their farm.
