This map identifies the potential suitability for subirrigation of land in the 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. A field assessment of any site is needed when evaluating a potential project. Watch the tutorial video for background and instructions for using this tool.
The methods for developing this map are described in the Tool Documentation page and in the open-access paper Potential Suitability of Subirrigation For Field Crops in The US Midwest (Feng,Y. Frankenberger, J., Ackerson, J., and B. Reinhart, Transactions of the ASABE. 63(5): 1559-1570. doi: 10.13031/trans.13783).
GIS layers can be downloaded by state or accessed by other applications as a REST service, as described on the documentation page.
The Hillshade layer services were developed by Darrell Schulze (https://soilexplorer.net). The map service is hosted by the Purdue University Libraries and School of Information Studies.
