“…For example, for ZTL, spatial variability was supposed to be integrated, because the number of collectors was defined from previous studies where spatial variability had been tested [18]. The temporal variability was related to seasons with maximum values occurring in autumn.…”

-The effects of the clear-cutting of a 70-year-old Douglas-fir plantation on the chemical composition of soil solutions and on leaching of nutrients in drainage waters were observed by a continuous monitoring, six years before and three years after the cutting. Forest harvesting was made with very limited soil disturbances. Results showed that the concentration of weakly fixed solutions did not change but that the concentration of gravitational solutions of the upper soil layers drastically fell down after the cutting. The limited increase in nutrients leached with drainage waters was only due to the increase in the water flux, which is difficult to quantify because of the presence of ground vegetation. The monitoring of numerous fluxes before and after the clear-cutting could explain the specific behaviour of the soil solutions. The limited losses of nutrients the after clear-cutting in a potentially responsive ecosystem were unexpected. The initial hypothesis was that the decrease in the mineralization and nitrification rates observed after the cutting was related to a stimulating effect of Douglas-fir on the activity of soil nitrifyers.Douglas-fir / clear-cutting / soil solutions / nutrients / leaching Résumé -Effet de la coupe à blanc d'un peuplement de Douglas (Pseudotsuga menziesii F.) sur la composition chimique des solutions du sol et sur le flux d'éléments drainés. Les effets de la coupe à blanc d'une plantation de Douglas de 70 ans ont été observés sur la composition chimique des solutions du sol et les pertes d'éléments par drainage, par un suivi mensuel pendant 6 ans avant, et 3 ans après la coupe. L'exploitation du peuplement a été réalisée avec une perturbation minimum du sol. Les résultats montrent que les solutions liées ont peu évolué après la coupe, alors que le changement des solutions libres a été drastique dans les horizons de surface du sol. Malgré des incertitudes sur le rôle de la végétation spontanée, le drainage d'éléments n'a pas fortement augmenté après la coupe. La prise en compte de l'ensemble des flux mesurés dans cette étude semble pouvoir expliquer les observations. Les pertes limitées après la coupe d'une plantation où l'activité nitrifiante était élevée avant la coupe étaient inattendues. L'hypothèse avancée est l'arrêt du contrôle stimulateur des populations nitrifiantes du sol après la coupe du Douglas. Douglas / coupe-à-blanc / solutions du sol / éléments nutritifs / lixiviation

Sr ratios in stream water behave in 3 different ways depending on moisture and on hydrological conditions prevailing in the catchment. During low water flow periods (discharge < 9 l/s), a positive linear relationship exists between Sr isotope ratio and discharge, indicating the influence of radiogenic waters draining the saturated area during storm events. During high water flow conditions, rising discharges are characterized by significantly less radiogenic waters than the recession stages of discharge. This suggests a large contribution of radiogenic waters draining the deep layers of the hillslopes during the recession stages, particularly those from the more radiogenic north-facing slopes. These results allow one to confirm the negligible instantaneous incidence of rainwater on stream water chemistry during flood events, as well as the existence in the catchment of distinct contributive areas and reservoirs. The influence of these areas or reservoirs on the fluctuations of Sr concentrations and on Sr isotopic variations in stream water depends on both moisture and hydrological conditions. Hence, on a same bedrock type, 87 Sr/ 86 Sr ratios in surface waters can be related to flow rate. Consequently, discharge variations must be considered as a pre-requisite when using Sr isotopes for calculating weathering rates in catchments, particularly to define the range of variations of the end-members.

“…Results highlight significant variations in the nitrogen cycle as a consequence of higher nitrogen inputs, ranging from mineralisation and nitrification (Aber et al, 1995) to changes in species richness (Stevens et al, 2004), composition (Krupa, 2003;De Vries et al, 2007;Bobbink et al, 2010) or relative abundance (Gilliam, 2006). Moreover, leaching of nitrogen from soils involves a concomitant leaching of base cations (Dambrine et al, 1995), further threatening plant nutrient balances. One way of appreciating overall nitrogen equilibrium in the soil is to consider the balance between nitrogen inputs into the ecosystem and nitrogen immobilisation and uptake (UNECE, 2004), where nitrogen leaching occurs when inputs are greater than immobilisation and uptake.…”

A B S T R A C TAtmospheric N deposition is known to severely impact forest ecosystem functioning by influencing soil biogeochemistry and nutrient balance, and consequently tree growth and overall forest health and biodiversity. Moreover, because climate greatly influences soil processes, climate change and atmospheric N deposition must both be taken into account when analysing the evolution of forest ecosystem status over time. Dynamic biogeochemical models have been developed to test different climate and atmospheric N deposition scenarios and their potential interactions in the long term. In this study, the ForSAFE model was used to predict the combined effect of atmospheric N deposition and climate change on two temperate forest ecosystems in France dominated by oak and spruce, and more precisely on forest soil biogeochemistry, from today to 2100. After a calibration step and following a careful statistical validation process, two atmospheric N deposition scenarios were tested: the current legislation in Europe (CLE) and the maximum feasible reduction (MFR) scenarios. They were combined with three climate scenarios: current climate scenario, worst-case climate scenario (A2) and best-case climate scenario (B1). The changes in base saturation and inorganic N concentration in the soil solution were compared across all scenario combinations, with the aim of forecasting the state of acidification, eutrophication and forest ecosystem recovery up to the year 2100.Simulations highlighted that climate had a stronger impact on soil base saturation, whereas atmospheric deposition had a comparative effect or a higher effect than climate on N concentration in the soil solution. Although deposition remains the main factor determining the evolution of N concentration in soil solution, increased temperature had a significant effect. Results also highlighted the necessity of considering the joint effect of both climate and atmospheric N deposition on soil biogeochemistry.
