英文文献作者:Dobbs, Thomas L.
英文文献摘要:
Labor intensity and returns to labor and management are compared for sustainable (alternative), conventional, and reduced tillage farming systems in the Northern Great Plains, using 7 years of data from a study in South Dakota running through 1992. Implications for farm size of substituting sustainable for conventional systems are examined.
