e-RA provides a permanent managed database for secure storage of data from Rothamsted's Long-term Experiments, the oldest, continuous agronomic experiments in the world. Together with the accompanying meteorological records, associated documentation and sample archive, it is a unique historical record of experiments that have been measured continuously since 1843.

  • Sites: Rothamsted Research has experimental arable farms across four sites in England, the original and most important is at Rothamsted, Harpenden (since 1843), with others at Woburn (since 1876), Brooms Barn (since 1962) and Saxmundham (1965-2010).
  • Experiments: Lists the main long-term experiments, grouped by research farm. Each experiment is described extensively and has a list of all the collated datasets currently available for it, supporting documentation, site details, history and images.
  • Experiment Data: The collated datasets currently available for the long-term experiments. Includes advice on copyright, appropriate credits, data quality and how to access the three different types of datasets. More datasets are being created and availability will be announced on Twitter.
  • Meteorological Data: Daily meteorological data is recorded at three of the Rothamsted Research sites: Rothamsted, Woburn and Brooms Barn. Summary data is available for Saxmundham. This section provides information on the available collated datasets plus data collection and processing methods, advice on copyright, appropriate credits, data quality and how to access the three different types of datasets. We also provide educational activities and datasets for schools.
  • About: Information on the e-RA project, who to contact, how to give credit and news on Twitter.
