A heavy clayland site, representative of 2 million hectares of similar soils in lowland England, where agricultural experiments were conducted for over 50 years. The farm system was based on autumn sown combinable crops and grassland. Hedges and ditches contributed to biological diversity. Please note: ECN monitoring was discontinued at Drayton at the end of 2013. However, data continue to be available.
