... The accuracy of the modelled effect of tree species selection, stand thinning and harvesting on soil C stock changes depends on the accuracy of the quantity and quality of C input into the litter compartment (Table 1). Some soil C model variables (e.g., tree species, site index, frequency and intensity of thinning, length of rotation and handling of harvest residues) can control the intensity and timing of C input into litter compartment (Eliasson et al., 2013;Kaipainen et al., 2004;Moreaux et al., 2020;Pérez-Cruzado et al., 2012;Wutzler and Mund, 2007). These variables can interact with and be modified by others in the model. ...

... Alternatively, soil P exchangeability can be determined by using isotopic tracers. The 32 P or 33 P isotopic exchange kinetics (IEK) are used to quantify how many inorganic P ions can be exchanged between the soil solution and the soil solid phase and thus can become plant available within a specific time frame (Frossard and Sinaj 1998;Frossard et al. 2011). This dynamic perspective on soil P availability has proven useful to better understand the influence of long-term P fertilization strategies on the availability of soil P and soil P fluxes (Oehl et al. 2002;Borda et al. 2014;van der Bom et al. 2019;Lemming et al. 2019). ...

... Reduced tillage or no-tillage (high controversy) (Dimassi et al. 2014) Restriction of OM access to decomposers Enhanced substrate-decomposer contact at the macroscopic scale (mulch incorporation, grinding to reduce substrate size) (Angers et al. 1997) or at the microscopic scale (aggregate reorganization) (Six et al. 2000) Erosion control (Sun et al. 2015) Accumulation of large amounts of plant residues at the soil surface where decomposer activity is most intense, instead of redistributing it over the soil profile Increase in N 2 O emissions (Guenet et al. 2021) the energy produced. Finally, soil fertility and production capacity should be carefully addressed, since biomass export affects not only C stock but also nutrient stocks (Achat et al. 2015;Durante et al. 2019;Legout et al. 2020). Under low fertility conditions, practices that favor the return of harvest residues to the soil should be encouraged. ...

... Forests are large and persistent sinks for atmospheric carbon dioxide (CO 2 ; Pan et al., 2011) and large-scale afforestation and reforestation have been suggested as methods for mitigating climate change through carbon sequestration (Law et al., 2018;Nave et al., 2018;Bastin et al., 2019;Pugh et al., 2019;Domke et al., 2020). However, intensification of forestry (Kastner et al., 2021), including removal of organic residues for bioenergy (Daiogloua et al., 2019), has led to concern about sustainability of base-cation supply (Achat et al., 2018;Akselsson et al., 2019), and better understanding of the ecological and biogeochemical consequences of different management practices is needed (Palmer, 2021). ...

... This was the case during wet years in our study systems, as we found that competitive effects of neighbouring plants were higher in siliceous communities developed under lower drougth-stress conditions on siliceous soils compared to calcareous communities developed under higher stress conditions on calcareous soils. This result is consistent with Grime (1974) that suggested a higher competition in benign environments, and also in agreement with other studies that found strong competition on siliceous soil (Aerts et al. 1991;Delerue et al. 2018). To summarize, we showed in this study that species from siliceous communities growing in low-stress conditions have a strong competitive effect in their home community. ...

... Phosphorus (P) is one of the major and essential plant nutrients after nitrogen (N) and potassium (K) for rice and it has often been artificially applied through fertilizers for the last few decades to increase rice production (Kvakić et al. 2018;Saraiva et al. 2022). The excess application of N, P, and K fertilizers resulted in contamination of the groundwater and eutrophication of water ecosystems (Hagab, Kotp, and Eissa 2018). ...

... Les gestionnaires privés et publics des forêts tirent en effet la plupart de leurs revenus de la production de bois. Or, cette production est menacée par les changements climatiques, comme le montrent des études projetant une baisse de la productivité moyenne des forêts européennes, liée à une détérioration de l'état sanitaire des arbres (Roux & Dhôte, 2017). Pour diversifier leurs revenus et équilibrer leurs dépenses, certains forestiers pourraient donc adopter des approches économiques émergentes en France ou ailleurs. ...

... 2020). Augusto et al. (2017) observed the association of different P pools with soil properties under different land uses. The positive relationship between NaHCO 3 -P I and NaOH-P I with available P forms (P and M-P) suggested that this pool supply the available P for microbes and plant uptake. ...

... Surface water eutrophication has received wide attention for decades because of the excessive surface runoff of phosphorus (P) from agricultural soils into waters, which has posed a severe threat to aquatic ecosystems and also presents a huge challenge for water dephosphorization [1,2]. The biological method usually referred to as the activated sludge treatment, is capable of removing most phosphorus by phosphorus-accumulating bacteria, but for trace level of phosphorus (e. g., below 0.1 mg P/L) in waters/wastewaters, its efficiency is often limited [3,4]. ...
