520			_aReasons for differences in rates of adoption of conservation tillage were investigated. Investment requirements for acquisition of management skills are larger per unit produced on smaller farms. The transition from conventional to no-till practices requires relatively more investment in management skills for some crops. Least-cost machinery complements were estimated for two wheat production systems and four farm sizes. If the machinery complement must be adjusted, adoption of conservation tillage will be slower on smaller farms on which machinery is replaced less frequently. Differences in rates of adoption byfarm size occur because of
