Abstract

National audience; Siberian studies performed over the last decades have detected a general increase in temperature and an increase in winter precipitation leading to a thicker snow pack. Climate models predict an amplification of these trends and indicate that the huge territory of the western Siberian plains will become suitable for agriculture. However, the projections do not consider soil fertility - a key issue for agricultural sustainability. The intention of our study is to test whether the predicted increase in snow precipitation will change the soil water fluxes, soil organic matter (SOM) decomposition, and the rate of nutrient release caused by reduced soil freezing. Investigations were performed in forests and grasslands close to Barnaul, in the steppe zone, and close to Tomsk, in the taiga zone. The sites were characterized for their climate, snow cover, pedoclimate and root patterns. A pair plot experiment was conducted to investigate the effect of snow thickness on soil temperature, moisture, and on the release of nutrients during SOM decomposition. Snow cover was artificially increased in the treatment plot and was undisturbed in the control plot. The impact of snow thickness on soil moisture and temperature was continuously monitored over one year. The release of nitrogen (N) from decaying litter was investigated using 15N isotope tracing. Enzyme activities relevant to the release of N and phosphorus (P) from SOM were measured. At all sites, N and P stocks were large, with organic P representing a high proportion of total P in the topsoil. The increase of snow cover raises the soil T°C over winter and enhances the soil water content after snowmelt. It impacts enzyme activities and the release of N from decomposing litter. These results showed that climate change in Western Siberia may affect soil fertility and the potential of soils to sustain agriculture after conversion of forest and grassland into cropland.

Abstract

International audience; Phosphorus (P) is a critical limiting factor of plant growth and production in many ecosystems, which often require to be fertilized. However, there is an increasing concern regarding appropriate local and global management of phosphorus resources, since the existing finite phosphate reserves are rapidly being depleted. This implies to understand what processes (biological, physico-chemical) are governing soil P availability in agroecosystems, and in particular in forests, which will be increasingly managed for their C-sink potential in the future. We characterized the P status in forest soils of the largest managed pine forest in Europe (Landes of Gascogne, southwest of France) using isotopic and extraction methods, as well as modelling approaches. Total P concentration in topsoils were extremely low, ranging from 7 to 195 mg Pkg-1. The concentration of phosphate ions in solution decreased with depth and was related to the Al and Fe oxide content, which controlled the diffusion of P from the soil solid phase to the solution. The gross amount of diffusive P in one week as determined by 32P isotopic dilution in batch experiments was low, ranging from 0.2 to 52 mg P kg-1 in the topsoil layer, and could be predicted by pedotransfer functions built on the Al and Fe oxide and soil organic matter contents. Organic P represented 80% of total P in litter and 60% in the surface mineral soil layer, suggesting a higher contribution of biological processes to soil P cycling. Biological mineralization of organic P was quantified using a long-term incubation study (154 days) of a low-sorbing soil labelled with 33P, associated with a batch experiment with 32P labelled soil: gross mineralization of dead soil organic matter and diffusive phosphate P were low (

Abstract

International audience; The fate of carbon in the soil plant system was followed by using pulse-labelling of 10 m tall trees in the field with 13 CO2 for a short period of time. The study is conducted on three tree species (beech, oak and pine) that are among the major species in European forests. Trees are labelled at three distinct phenological phases during the growing season. The assimilated 13 C by plants during the pulse labelling was then tracked in soil CO2 efflux with a high temporal resolution using tuneable diode laser absorption spectrometry and in the microbial compartment from soil cores (root + mycorrhiza transfer) and in mesh cores that permit the ingrowth of mycorrhiza hyphae but exclude roots (no-root cores).

Abstract

National audience; Ectomycorrhizal fungi (ECM) and their associated mycorrhizosphere bacteria (MB) play a major role in phosphorous (P) nutrition of maritime pine, particularly in the Landes forest ecosystem considering the low bioavailability of P in its sandy-acidic soils. In order to characterize the MB associated to ECM, three collection campaigns of ECM root tips were performed from autumn 2005 to autumn 2006 throughout three forest stations. Five MB and nine ECM genera were identified overall through sequencing of 16S rDNA and mitochondrial large subunit rDNA fragment respectively. Dramatic seasonal changes were observed in the different MB-ECM associations especially in Burkholderia–Lactarius and Bacillus–Russula that were the most abundant ones. P-solubilizing ability of MB was shown to be taxon-dependent with a large majority of P-solubilizing isolates among Burkholderia, Pseudomonas and Paenibacillus contrary to Bacillus. Relationships between functional diversity of the MB-ECM associations and bioavailability of soil P remain to be investigated.

Abstract

International audience; The objectives of the present work were (a) to quantify the effects of wood ash on forest ecosystems through a meta-analysis approach associated with a detailed review of the literature (mainly composed of work carried out in Nordic countries) and (b) to extrapolate the effects on forest growth to other contexts (i.e. warm temperate countries) by identifying the cases for which wood ash applications can be beneficial to forest production. Three databases were built regarding the effects of wood ash on soil (151 observations; 33 experimental field trials), on nutrient concentrations of tree foliage (68 observations; 28 trials) and on annual stem biomass growth rate (70 observations; 27 trials). We obtained information on the wide variability of ash properties due to differences in burnt compounds, combustion processes and ash conditioning. Two important properties of wood ash are its high pH value and neutralizing capacity. These properties result in biochemical modifications of forest soils limed with ash. In the short term, soil solution composition was dramatically modified. Intense peaks of the K, Na or SO4 concentrations were observed, resulting from the dissolution of salts contained in ash. At the same time, Ca and Mg concentrations increased as the carbonate pool of wood ash started to dissolve. The consequence of this dissolution process was an increase in the pH in all the soil phases. These modifications increased the activity of the soil microflora and some isolated peaks in the mineralization of soil organic matter may be observed in mineral soils. In the longer term, that is to say after the first year following ash application, only the effect on the acidity status of the soil remained significant. The effects of ash addition on forest ecosystems usually increased with the dose and were more pronounced with loose ash compared to aggregated ash. The addition of wood ash into forest ecosystems increased the foliar Ca status of trees. Some modifications of other nutrients, like P or K, were also observed but only for a few years after treatment. For most stands growing on mineral soils of Nordic countries, this treatment did not result in an increase in tree growth, probably because of the absence of N in the ash. For stands growing on organic soils of the same area, this input, associated with a long-lasting increase of soil organic matter mineralization, was sufficient to improve tree growth significantly (median=+59% compared to the control). For soils located in warm temperate regions, similar responses are expected for organic soils. For mineral soils, the wood ash application is expected to be suitable for stands showing deficiencies in K, Ca or Mg. Ash may contain high amounts of toxic heavy metals such as Cd. The bioavailability of most of these elements appeared to be very low in a forest context. No contamination of food chains has been observed, except possibly via some species of fungi, and heavy metals remain in the forest litter or in the topsoil. Based on all the reviewed results, several guidelines for wood ash application into forest ecosystems are proposed. Wood ash application should be restricted to acidic soils. Applications should consist of low doses of a stabilized ash form. Wood ash should be applied to adult stands rather than onto seedlings.
