Greater emphasis is being placed on indicators of agri-environmental efficiency of organic production systems. Linking environmental measures with profitability measures based on net income is the only way to develop such indicators. A stochastic production frontier model that explicitly incorporates farm decisions about acquiring and managing organic soil-improving inputs is used to measure efficiency. The results confirm that on-farm self-sufficiency in soil-improving inputs is positively related to farm-level efficiency.
人们越来越重视有机生产系统的农业环境效率指标。将环境措施与基于净收入的盈利能力指标联系起来是制定此类指标的唯一途径。一种明确纳入农场关于获取和管理有机土壤改良投入决策的随机生产前沿模型被用于衡量效率。结果证实，农场在土壤改良投入方面的自给自足与农场层面的效率呈正相关。
