State borders and state-level data were found to be poor guides for policy. Mapping of input criteria suggest strong regions of high- and low-input farm management practices, demonstrating that an empirical knowledge of where input-intensive farms exist will enhance one{\textquoteright}s ability to design and implement policies for low-input agriculture. Cluster analysis results reinforce the notion that conventional regions of agriculture that rely strictly on climate, geomorphology, and crop production are insufficient for assessing appropriate policy targets toward improved farm management. Four-state results offer encouragement for expanding an integrated, data-based perspective to the entire United States.}, issn = {0022-4561}, URL = {https://www.jswconline.org/content/45/1/128}, eprint = {https://www.jswconline.org/content/45/1/128.full.pdf}, journal = {Journal of Soil and Water Conservation} }
