e-RA: the electronic Rothamsted Archive

Case Studies

Data held in e-RA provide a unique historic record from experiments that have measured the effects of agricultural practices on soils, crops and associated ecosystems continuously for over 160 years. Together with the retrospective analysis of archived material from the Rothamsted Sample Archive, these data continue to reveal new insights and important findings of relevance to today's agriculture and the wider environment.

The following Case Studies illustrated as posters show some of the ways in which data from e-RA and the Sample Archive have been used.

1. Long-term dynamics in wheat of Phaeosphaeria nodorum and Mycosphaerella graminicola. Shaw MW, Bearchell SJ, Fitt BDL and Fraaije BA.
