Integrated evaluation of greenhouse gas emissions (CO2, CH4, N2O) from two farming systems in southern Germany
Abstract Agricultural practices contribute to emissions of the greenhouse gases CO2, CH4 and N2O. The aim of this study was to determine and discuss the aggregate greenhouse gas emission (CO2, CH4Expand

Low temperature control of soil denitrifying communities: kinetics of N2O production and reduction
Abstract To explore the reason for reported high field fluxes of nitrous oxide (N 2 O) from temperate soils in winter and early spring, we investigated the temperature response of denitrifier N 2 OExpand

Seasonal variation of N2O and CH4 fluxes in differently managed arable soils in southern Germany
Agricultural practices are assumed to contribute significantly to the increase in atmospheric nitrous oxide (N 2 O) concentrations observed in the last decades, and they might influence theExpand

N2O emissions and product ratios of nitrification and denitrification as affected by freezing and thawing
Abstract Agricultural soils contribute significantly to atmospheric nitrous oxide (N2O). A considerable part of the annual N2O emission may occur during the cold season, possibly supported by highExpand

Influence of cattle wastes on nitrous oxide and methane fluxes in pasture land
Agricultural practices are assumed to contribute significantly to the increase in atmospheric N{sub 2}O concentrations observed in the last decades, and they might influence the consumption ofExpand

The N2O product ratio of nitrification and its dependence on long-term changes in soil pH
The contribution of nitrification to the emission of nitrous oxide (N2O) from soils may be large, but its regulation is not well understood. The soil pH appears to play a central role for controllingExpand

Comparison of N2O emissions from soils at three temperate agricultural sites: simulations of year-round measurements by four models
Nitrous oxide (N2O) flux simulations by four models were compared with year-round field measurements from five temperate agricultural sites in three countries. The field sites included anExpand

Comparison of denitrifying communities in organic soils: kinetics of NO−3 and N2O reduction
Abstract Our aim was to determine whether intrinsic differences in the denitrifier communities existed in farmed organic soils from three different sites (Germany, Sweden and Finland) on which fieldExpand

Overwinter greenhouse gas fluxes in two contrasting agricultural habitats
Mid-day field fluxes of nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4) were measured during late winter/early spring in an arable field and an adjacent fallow in southern Germany. On theExpand

Robotized incubation system for monitoring gases (O2, NO, N2O N2) in denitrifying cultures.
As genomic data for bacteria are unraveled at an increasing speed, there is a need for more efficient and refined techniques to characterize metabolic traits. The regulatory apparatus forExpand
