e-RA: the electronic Rothamsted Archive

The electronic Rothamsted Archive (e-RA) provides a permanent managed database for secure storage of data from Rothamsted's Classical 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 for nearly 170 years. Users have easy access to experimental data and specialist background information on the effects of agricultural practices on soils, crops and associated ecosystems.

Currently, e-RA holds records of yields and other data for the Broadbalk winter wheat, Park Grass permanent grassland, Hoosfield spring barley and Alternate Wheat and Fallow Classical experiments. Meteorological data from Rothamsted, Brooms Barn and Woburn are also available. In a recent development, data from the North Wyke Farm Platform is being added to e-RA. The links, left, will lead you to background information on the experiments or the data. All Datasets shows a full list of current datasets which are continually being added to.

The data in e-RA are available for scientific research, but remain the property of Rothamsted Research and the Lawes Agricultural Trust. Most of the data held within e-RA are password-protected and access is subject to our Data Access Policy. The Open Access data are available to all, no password is required, although users are required to acknowledge Rothamsted Research as the data source.

The importance of e-RA, the Long-Term Experiments and Sample Archive have been recognised by the BBSRC in awarding them National Capability (NC) status. NC is defined as being a strategic component of the international research base. NCs are by definition externally facing and engaged with the user community.

For further information contact the e-RA Curators. Data can be extracted on your behalf.
