This map identifies the potential suitability for subirrigation of land in the Upper Midwestern United States. It identifies agricultural land that has a restricting layer that causes the water table to rise, permeable soil above the restricting layer that allows the water to move horizontally between the tile drains, flat topography that allows economical systems, and is likely to be tile-drained. Field assessment of any site is needed when evaluating a potential project. Specific criteria are explained here, and in the related publication Feng,Y. Frankenberger, J., Ackerson, J., and Reinhart, B., Transactions of the ASABE. In Review.
