Linkage between N2O emission and functional gene abundance in an intensively managed calcareous fluvo-aquic soil
The linkage between N2O emissions and the abundance of nitrifier and denitrifier genes is unclear in the intensively managed calcareous fluvo-aquic soils of the North China Plain. We investigated the abundance of bacterial amoA for nitrification and narG, nirS, nirK, and nosZ for denitrification by in situ soil sampling to determine how the abundance of these genes changes instantly during N fe...
متن کاملFirst on-line isotopic characterization of N2O above intensively managed grassland
The analysis of the four main isotopic N2O species (NNO, NNO, NNO, NNO) and especially the intramolecular distribution of N (“site preference”, SP) has been suggested as a tool to distinguish source processes and to help constrain the global N2O budget. However, current studies suffer from limited spatial and temporal resolution capabilities due to the combination of discrete flask sampling wit...
متن کاملGreenhouse gas budget (CO2, CH4 and N2O) of intensively managed grassland following restoration.
The first full greenhouse gas (GHG) flux budget of an intensively managed grassland in Switzerland (Chamau) is presented. The three major trace gases, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) were measured with the eddy covariance (EC) technique. For CO2 concentrations, an open-path infrared gas analyzer was used, while N2O and CH4 concentrations were measured with a recentl...
متن کاملErosion of upland hillslope soil organic carbon: Coupling field measurements with a sediment transport model
[1] Little is known about the role of vegetated hillslope sediment transport in the soil C cycle and soil-atmosphere C exchange. We combined a hillslope sediment transport model with empirical soil C measurements to quantify the erosion and temporal storage of soil organic carbon (SOC) within two grasslands in central California. The sites have contrasting erosional mechanisms: biological pertu...
متن کاملSpatial variability and hotspots of soil N2O fluxes from intensively grazed grassland
One hundred N2O flux measurements were made from an area of intensively managed grazed grassland in central Scotland using a high-resolution dynamic chamber method. The field contained a variety of features from which N2O fluxes were measured including a manure heap, patches of decaying grass silage, and areas of increased sheep activity. Individual fluxes varied significantly across the field ...
