Jolly A1 William M. Edwards A1 Donald C. Erbach YR 1983 UL http://www.jswconline.org/content/38/3/291.abstract AB Farm-level risks and returns were examined for corn and soybeans grown in rotation using three conservation tillage systems. 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.
