Respiration of soils from different land use plots on the Highfield experiment (Rothamsted) after addition of barley shoot powder and repeated dry:wet disturbances

The dataset contains the results of an experimental and modelling study to investigate the resilience of soils sampled from different land-uses to repeated drying and rewetting disturbances. Soils were sampled from the arable, grass, arable to grass reversion, grass to arable reversion and fallow plots of the Highfield long term experiment at Rothamsted Research, Harpenden, UK. They were then subjected to prescribed and controlled repeated drying and rewetting stresses. Prior to disturbance and after 1, 2, 3, 4, 7 and 12 drying and rewetting cycles barley shoot powder (5 mg) was added to the 0.5g soil samples and the respiration response observed at 6 min resolution. This dataset contains the raw respiration data from the soil samples as well as model parameters of a model fitted to these respiration profiles in order to characterise their response shape.<br>This work was supported by the Biotechnology and Biological Sciences Research Council [grant numbers BB/J000671/1, BB/J000671/2]; and the UK Department of Environment, Food and Rural Affairs).
