Plot Map Considerations

  • Site maps included below will often include plot numbers; these align with the plot identifiers listed with the data.
  • The maps however may contain treatment codes that do not match the data; these are unique to that location and were changed afterwards to align with codes used across Sustainable Corn CAP sites.
  • Some experiments include treatments beyond those that were part of the Sustainable Corn CAP which can be seen in the plot map.

Data originating from research sites that have subsurface tile drainage installed are included here. They are not included under the Research Data tab because data are collected on a time series basis with the user selecting the aggregation preferred for export. Please note that additional data such as management operations, plot identifiers, data dictionary, and site history for these drainage research sites are included under the Research Data tab. It is strongly recommended to download these supporting data to properly interpret and synthesize water data contained here.

Datasets include:

Tile flow and water quality data for the BRADFORD.A experimental site are not included here due to conditions that are distinct from other drainage sites. Drainage tile were installed in the clay layer of the soil profile which impacted the amount of water through the system and out from the site. Contact sustainablecorn@iastate.edu for access to this data.


Supplementary weather data are available for Sustainable Corn CAP research sites and are provided from nearby weather networks. These data are most appropriate to use with these research sites because of proximity. The data are collected from a variety of sources, including the National Climatic Data Center, National Weather Service, and State Climatologists with curation and management by Iowa Environmental Mesonet. These entities revise their data and will produce updated values that are reprocessed into this archive.

How shall the output values be separated?

The downloaded data file name will contain the weather station identifiers if you request data from 9 or less sites. For requests over 9 sites, the filename will simply be "changeme". Refer to the drop-down above for reminder as to which site it corresponds with.

On-site weather stations existed at some research sites to provide finer resolution weather data as compared to the networked weather data which can be a mile or more away. This on-site weather data is especially valuable for precipitation amounts as that will vary more spatially than temperature or wind.

On-site weather stations tend to be less robust of instrumentation however than the weather data included under the first tab. It is recommended to use this on-site data as a secondary data set to refine the networked data. It is expected that the temperature and wind values will be near identical between the stations but the precipitation amounts will vary.

Social economic research was conducted and included a survey of 4,778 farmers in 11 Corn Belt states and 156 one-hour, in-person farmer interviews. The data cannot be released due to anonymity issues but are available in aggregated format across watersheds in the region. These aggregated data and maps are available in two publications:

Farmer Perspectives on Agriculture and Weather Variability in the Corn Belt: A Statistical Atlas, Volume 1

This first atlas (Volume 1) provides data regarding farmer beliefs and concerns about climate change, attitudes toward adaptation and mitigation, perceived capacity to deal with the impacts and recent experiences with extreme weather events. Delineated by watershed, this collection of tables and maps provides the results of a USDA-NIFA-supported survey, conducted in 2012, of 4,778 farmers in 11 Corn-belt states.

Farmer Perspectives on Agricultural Practices, Information, and Weather Variability in the Corn Belt: A Statistical Atlas, Volume 2

This second atlas (Volume 2) provides additional results from a 2012 survey of 4,778 farmers in 11 Corn-belt states. Here, the focus is upon farmers' specific behaviors, beliefs about climate and weather, and the tools they utilize to make farm decisions. You will find information covering timing of farming practices and farming decisions, whether and how farmers use weather information when making farming decisions; a detailed look at the influence of agricultural advisors in farmer decision making processes; farmers' personal experiences regarding weather and risks; and plans and efforts of farmers to adapt to and manage for weather and climate variability and risk.
