Influence of tree species on gross and net N transformations in forest soils Inra
Zeller, B.; Recous, S.; Kunze, M.; Moukoumi, J.; Colin-Belgrand, M.; Bienaime, S.; Ranger, J.; Dambrine, E..
Nous avons mesuré les flux de minéralisationnette d’azote au cours d’une incubation de quatre semaines et les flux bruts d’azote au cours d’une incubation de deux jours dans 6 sols prélevés dansune comparaison d’espèces forestières. Nous avons comparé les horizons A1 d’un taillis sous futaie (TSF) de Fagus sylvatica et de cinq plantationsadjacentes de 25 ans de Fagus sylvatica, Picea abies, Quercus petraea, Pinus laricio et Pseudotsuga menziesii. Les taux bruts ont été mesurés 48 haprès l’addition de 15NH4 et 15NO3. La minéralisation brute a été calculée à partir de la dilution de 15NH4 et la nitrification brute à partir de la dilutionde 15NO3 mais aussi de la production de 15NO3 à partir de l’apport de 15NH4. La minéralisation brute et nette est la plus...

N deposition, N transformation and N leaching in acid forest soils Inra
Jussy, J.H.; Colin-Belgrand, M.; Dambrine, E.; Ranger, J.; Zeller, B.; Bienaimé, S..
Nitrogen deposition, mineralisation, uptake and leaching were measured on a monthly basis in the field during 2 years in six forested stands on acidic soils under mountainous climate. Studies were conducted in three Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] plantations (D20: 20 year; D40: 40 yr; D60: 60 yr) on abandoned croplands in the Beaujolais Mounts; and two spruce (Picea abies Karst.) plantations (S45: 45 yr; S90: 90 yr) and an old beech (Fagus sylvatica L.) stand (B150: 150 yr) on ancient forest soils in a small catchment in the Vosges Mountains. N deposition in throughfall varied between 7–8 kg ha–1 year–1 (D20, B150, S45) and 15–21 kg ha–1 yr–1 (S90, D40, D60). N in annual litterfall varied between 20–29 kg ha–1 (D40, D60, S90), and 36–43...
