Description
The research was conducted at a demonstration site on a private farm located near Lakeview, OH. The soil series was Millford silty clay loam (fine, mixed, superactive, mesic Typic Endoaquolls), which comprised areas ranging from very poorly to somewhat poorly drained.
There were 2 research plots, one with conventional drainage and another with controlled drainage. In 2012 drainage treatments were swapped between plots. Subsurface drainage lines were installed at a depth of 3.0 to 3.5 ft with lateral spacing of 50 ft in both plots. Size of individual plots were 19 and 29 ac.
The lateral drains from each zone discharged to a main pipe that was routed through an inline water level control structure before discharging into the drainage ditch. Within the control structure, stop-logs were used to adjust the outlet elevation to different heights to accommodate the controlled drainage goal during different seasons. Typically, the controlled drainage outlet elevation was set approximately 1 ft below the ground surface after harvest until early April (a few weeks before planting). The outlet elevation was then lowered (i.e., stop-logs removed) to accomplish planting and crop establishment. Then beginning in mid to late June (4 to 8 weeks after planting), the outlet elevation was set 2 to 3 ft below the ground surface, where it remained until mid-September (a few week before harvest). The outlet elevation at the conventional drainage zone was set to always allow unrestricted free drainage.

To access spreadsheets for Y1 priority data, click on the corresponding hyperlinks below. Each spreadsheet contains multiple worksheets (one for each relevant year). You can click on the year tabs at the bottom of the spreadsheet page to switch between them.
Data should not be aggregated for entry into the team database but entered on the smallest scale possible (plot-level, sensor-based, etc.). All data will be entered by calendar year also - not hydrological year or crop year.
