Abstract	Maine consistently ranks in the top ten potato (Solanum tuberosum L.) production areas though yields are substantially lower than the mid- and western USA. Geospatial frameworks help resolve patterns and trends in production environments (at multiple scales) that may enable improvements in adaptive management strategies which enhance yield, increase whole-farm profitability, and foster sustainable land use. Results from geospatial integration of remotely-sensed cropland (2008–2010) and soil datasets for Maine indicate an estimated 61,900 ha in potato production with 62 % and 27 % on prime farmland (PF) and farmland of statewide importance (FSI), respectively. Geospatial analyses of other agri-environmental indicators indicate close to 85 % of these potato production soils are classified as either “potentially highly erodible” (PHEL) or “highly erodible” (HEL). Therefore, at least 52,300 ha require the highest standards in soil conservation practices. Crop rotation patterns for potato, derived from the time-series geo-referenced datasets, help resolve actual cropping practices and facilitated evaluation of the benefits and economic impacts for select alternate crops.El Estado Norteamericano de Maine esta posicionado consistentemente entre las primeras diez áreas de producción de papa (Solanum tuberosum L.), aunque los rendimientos son substancialmente mas bajos que en el centro y el oeste de EUA. Los marcos de referencia geoespaciales ayudan a resolver patrones y tendencias en los ambientes de producción (a escalas múltiples) que puedan conducir mejoras en estrategias adaptativas de manejo que incrementen el rendimiento, las ganancias de la unidad de producción, y estimulen sustentabilidad en el uso de la tierra. Los resultados de la integración geoespacial de tierras de cultivo a sensor remoto (2008–2010) y paquetes de datos de suelo para Maine, indican una estimación de 61,900 ha en producción de papa con 62 % y 27 % en tierra de cultivo de primera (PF) y de tierra de cultivo de importancia (FSI) en el Estado, respectivamente. Los análisis geoespaciales de otros indicadores agroambientales señalan que cerca del 85 % de estos suelos de producción de papa están clasificados ya sea como “potencialmente altamente erosionables” (PHEL) o “altamente erosionables” (HEL). De aquí que por lo menos 52,300 ha requieren de los mas altos estándares de prácticas de conservación de suelos. Los patrones de rotación de cultivos para papa, derivados de las hojas de datos de series georeferenciadas en el tiempo, ayudan a resolver las prácticas actuales de cultivo y facilitaron la evaluación de los beneficios y de los impactos económicos para seleccionar cultivos alternativos.
