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 for over 170 years. Users have access to experimental data and specialist background information on the effects of agricultural practices on crops, soils and associated ecosystems.
Currently, e-RA holds records of yields, species composition and other data for the following Long-term experiments:
|Permanent grassland||Park Grass||1856|
|Spring barley||Hoosfield Barley||1852||Winter wheat||Alternate Wheat & Fallow||1856|
|Woodland||Geescroft & Broadbalk Wilderness||1880s|
Meteorological data for Rothamsted (from 1853), Woburn (from 1928) and Brooms Barn (from 1982) are also available.
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 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 we ask that users acknowledge Rothamsted Research as the data source.
Please contact the e-RA Curators to arrange a password, for further information, or to extract data on your behalf.
The e-RA database is part of the Long-term Experiments National Capability, which also includes the Long-Term Experiments, the Sample Archive and the Environmental Change Network. It is jointly funded by the BBSRC and the Lawes Agricultural Trust.
