Compared effects of long-term pig slurry applications and mineral fertilization on soil denitrification and its end products (N2O, N2) Inra
Dambreville, C.; Hénault, C.; Bizouard, F.; Morvan, T.; Chaussod, R.; Germon, J.C..
The long-term (9 years) effect of pig slurry applications vs mineral fertilization on denitrifying activity, N2O production and soil organic carbon (C) (extractable C, microbial biomass C and total organic C) was compared at three soil depths of adjacent plots. The denitrifying activities were measured on undisturbed soil cores and on sieved soil samples with acetylene method to estimate denitrification rates under field or potential conditions. Pig slurry applications had a moderate impact on the C pools. Total organic C was increased by +6.5% and microbial biomass C by ≥25%. The potential denitrifying activity on soil suspension was stimulated (×1.8, P<0.05) 12 days after the last slurry application. This stimulation was still apparent, but not...

Comparing indicators of N status of 50 beech stands (Fagus sylvatica L.) in northeastern France Inra
Andrianarisoa, K.S.; Zeller, B.; Dupouey, J.L.; Dambrine, E..
We compared different potential indicators of nitrogen (N) availability across 50 beech forests growing on a wide range of soils in northeastern France. Among the 50 sitesmeasured, high elevation acidic soils had the highest potential net N mineralization in the A horizon (PNM0–5 cm), while low elevation neutral and calcareous soils had the lowest (PNM0–5 cm). We found that (PNM0–5 cm) was negatively correlated with soil pH (R2 = 0.47***) and positively correlated with microbial C/N (R2 = 0.34***). However, when high elevation sites were excluded from analyses, the relationship between PNM0–5 cm and soil pH as well asmicrobial C/N became weaker (R2 = 0.23*** for both variables).Wefound no relationship between PNM0–5 cm and organic N concentration, soil...

Comparison of methods for measuring denitrifying activity in marine-sediments from the western mediterranean coast ArchiMer
Raymond, N; Bonin, P; Bertrand, Jc.
Different types of denitrification rates in coastal marine sediments from the Western Mediterranean coast (France) were simultaneously determined by varioUS C2H2 inhibition techniques: in situ denitrifying activity in intact cores or sediment slurries; DEA (Denitrifying Enzyme Assays); and potential activity. Denitrifying activity was also estimated by the use of kinetic parameters (Km and V(max)). Values for denitrifying activities in the top two centimetres ranged from 0 to 50-mu-moles of nitrous oxide produced per litre of sediment per day, and were similar when intact core or sediment slurries were used. DEA showed comparable values for all the study sites. The potential activity ranged from 298-600-mu-moles per litre per day. Estimated activity based...

Diversity of denitrifying microflora and ability to reduce N2O in two soils Inra
Chèneby, D.; Hartmann, A.; Hénault, C.; Topp, E.; Germon, J.C..
 The ozone-depleting gas N2O is an intermediate in denitrification, the biological reduction of NO3 – to the gaseous products N2O and N2 gas. The molar ratio of N2O produced (N2O/N2O+N2) varies temporally and spatially, and in some soils N2O may be the dominant end product of denitrification. The fraction of NO3 –-N emitted as N2O may be due at least in part to the abundance and activity of denitrifying bacteria which possess N2O reductase. In this study, we enumerated NO3 –-reducing and denitrifying bacteria, and compared and contrasted collections of denitrifying bacteria isolated from two agricultural soils, one (Auxonne, soil A) with N2O as the dominant product of denitrification, the other (Châlons, soil C) with N2 gas as the dominant product....

Effect of dissolved oxygen and carbon-nitrogen loads on denitrification by an aerobic consortium Inra
Patureau, D.; Bernet, N.; Delgenès, J.P.; Moletta, R..
Four samples of natural ecosystems and one sample from an activated sludge treatment plant were mixed together and progressively adapted to alternating aerobic/anoxic phases in the presence of nitrate in order to enrich the microflora in aerobic denitrifiers. Aerobic denitrifying performances of this mixed ecosystem at various dissolved oxygen concentrations and various carbon–nitrogen loads were evaluated and compared to those obtained with the aerobic denitrifier Microvirgula aerodenitrificans. The consortium and the pure strain exhibited an aerobic denitrifying activity at air saturation conditions (7 mg dissolved oxygen l–1), i.e. there was co-respiration of the two electron acceptors with significant specific nitrate reduction rates. Dissolved oxygen...
