A conventional moldboard plow system served as a benchmark. Potential economic incentives and barriers to adoption of conservation tillage were identified and measured. Short-run economic criteria favored conventional and full-width tillage systems. Higher residue systems were competitive after reallocation of labor and capital. Results indicate that short-run economic penalties may inhibit adoption of conservation tillage. ER -
