Rothamsted Research

where knowledge grows

Electronic Rothamsted Archive (e-RA)

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. 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.

National Capability

A national capability is a BBSRC-funded resource intended to benefit the scientific community in general. These can be facilities as well as opensource datasets. 

National Capabilities

Rothamsted Insect Survey

Operates two national networks for monitoring insect populations in the UK

North Wyke Farm Platform

Provides the research community access to a range of in situ state-of-the-art instrumentation in hydrologically isolated fields and farms to better address key issues in sustainable agriculture.


A database of interactions between pathogens and their hosts maintained at Rothamsted Research with international input.

Long-Term Experiments

These have been running since the mid 19th Century, provide a unique experimental system and archive of soil and plant samples.
