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 in the tool documentation, and in the related publication Feng,Y. Frankenberger, J., Ackerson, J., and Reinhart, B., Transactions of the ASABE. In Review.
The annual Drainage Design Workshop will be held in East Lansing, Michigan. This workshop is a collaboration between Michigan State University and Michigan Land Improvements Contractors Association. This two-day workshop focuses on planning and designing of subsurface (tile) drainage systems to meet both crop production and environmental objectives.
The dozers were crawling, the scrapers were filling with earth, and a dozen pieces of construction equipment were buzzing in all directions. It was the last week of July 2019, and Kelly Nelson was clearly in awe of speed and skill at which a new reservoir was taking shape on the 240-acre Grace Greenley farm in the northeast corner of Missouri.
Nick Hermanson of Story City has been utilizing drainage water recycling on his farms for several years. Drainage recycling utilizes ponds that hold water during the spring and early summer. The water is then applied to crop land during optimal times.
