This dataset contains research data compiled by the “Managing Water for Increased Resiliency of Drained Agricultural Landscapes” project a.k.a. Transforming Drainage. This project was funded from 2015-2021 by the United States Department of Agriculture, National Institute of Food and Agriculture (USDA-NIFA, Award No. 2015-68007-23193). Data are also available from a separate web-accessible application (drainagedata.org). At drainagedata.org, users can visualize the data with customized tools, query based on specific sites and measurements of interest, and access site photographs, maps, summaries, and publications. Additional data or edits made following the publication of this data here at USDA NAL Ag Data Commons will be posted under the Versions tab on drainagedata.org.

These data began in 1996 and include plot- and field-level measurements for 39 experiments across the Midwest and North Carolina. Practices studied include controlled drainage, drainage water recycling, and saturated buffers. In total, 219 variables are reported and span 207 site-years for tile drainage, 154 for nitrate-N load, 181 for water quality, 92 for water table, and 201 for crop yield.

The Transforming Drainage Project worked to advance the process of designing and implementing agricultural drainage systems for storing water in the landscape to improve the resiliency and productivity of agricultural systems. At each site, a control plot was paired with a plot with one of the following three practices to assess impacts.

  1. Controlled Drainage (CD) is the practice of using a water control structure to raise the depth of the drainage outlet, holding water in the field during periods when drainage is not needed.

  2. Drainage Water Recycling (DWR) diverts subsurface drainage water into on-farm ponds or reservoirs, where it is stored until it can be used by the crop later in the season through supplemental irrigation.

  3. Saturated Buffers (SB) remove nitrate from subsurface drainage water by diverting it into the buffer where it can be taken up by growing vegetation or removed by denitrification.

Intended use

This project generated data that can provide a comprehensive understanding of hydrologic, environmental, and agronomic processes in agroecosystems with subsurface drainage across several Midwest states and North Carolina. Scientists, modelers, producers, and policymakers can gain a unique insight into the impacts of drainage water management practices on water quantity and quality, as well as on crop yield. The data will be of great use for calibrating or validating hydrologic models at ever-larger scales (field, farm, and landscape), which can be coupled with projections from regional climate models to extrapolate the observed results to climate regimes not included within the study period.

Use limitations

Research data have been collected across 39 sites over a period of more than two decades. However, sites vary in the length of experimentation, years of available data, and variables reported. Most of the experiments were not coordinated at time of initiation, hence research data collected and protocols used vary among the sites. To ensure compatibility and integrity of the data, variables have been standardized across the sites and years as possible. We strongly recommend all users to reference the uploaded file detailing methods at each site used for collecting/measuring variables. Occasionally, site-specific protocols were not adhered to because of technical or environmental constraints resulting in missing or non-standard measurements (e.g. soil samples collected at different depths due to soil freezing). Monitoring instrumentation and data logger malfunctioning were main reasons for missing water data (e.g. depth of water table); care should be taken when interpolating or aggregating these data (e.g. when estimating monthly drain flow). Some of the missing drain flow data were filled in using a special imputation method developed by the project team and are available with the original drain flow data in this dataset. It should be noted that dielectric probes used to measure volumetric soil water content did not have soil-specific calibration. Therefore, syntheses of soil moisture data from different sites should be done with caution. Users should also be aware that at some sites, subsurface drainage systems were established at the onset of the project while others were drained for decades. Hence, the treatment effect and dynamics of certain measurements can differ based on length of history. We encourage everyone to become familiar with the history and details of each research site before starting data analysis.
