Denitrification and greenhouse gas emissions in natural and semi-natural terrestrial ecosystems [LTLS]

Data comprise monthly field measurements of in-situ denitrification rates in different land use types of the Ribble Wyre and Conwy catchments. The data include greenhouse gas emissions (methane, carbon dioxide, nitrous oxide), denitrification data (nitrogen and nitrous oxide) and soil properties data (nitrate, dissolved nitrogen, ammonia, bulk density, carbon to nitrogen ratio, dissolved organic carbon, moisture content, organic matter content, pH, temperature and water filled pore space).
The research was funded by the UK Natural Environment Research Council (NERC) grant (NE/J011541/1) awarded to Keele University and supported by the NERC Life Sciences Mass Spectrometry Facility Steering Committee.

Provenance & quality

During gas flux measurements the soil temperature and the volumetric water content at 10 cm depth were recorded next to each chamber using a soil thermometer (Kangaroo Thermistor Thermometer, Cole-Parmer) and a soil moisture probe (Hydrosense II, CS659, Campbell Scientific), respectively. Additionally, the air temperature and barometric pressure were recorded in each study site between the first and second sampling hour using a thermo-hygro-barometer (Comet, C4130, Sequoia Sensors). Five composite soil samples (0-10 cm) were collected with a hand auger from each study site after the end of the gas flux measurements within 50 cm of each plot. The samples were transported to the laboratory on ice and stored at 4 oC overnight. The next day visible stones and roots were removed manually and the soils were homogenized by manual mixing before laboratory analysis. The collars were moved to new random plots within each study site every three months to minimize any effects on greenhouse gas fluxes from repeated tracer application in the same plots. Next to every new plot an intact soil core (50 mm internal diameter, 10 cm long) was collected for the determination of soil bulk density and porosity.
