“…While plants are generally the main sources of nonmethane VOC emissions in most terrestrial ecosystems (Fehsenfeld et al, 1992;Fuentes et al, 2000;Penuelas et al, 2014), soil VOC emissions can represent 10-50% of the net forest canopy VOC flux depending on the ecosystem type and environmental conditions (Aaltonen et al, 2013;Janson, 1993;Schade & Goldstein, 2001). In other words, microbial VOC emissions from soil could be relevant to atmospheric chemistry given that soil and litter emissions of specific VOCs can be similar in magnitude those from aboveground vegetation (Potard et al, 2017;Schade & Goldstein, 2001).…”

Dynamics of carbon dioxide (CO2) emissions following the wetting of dry soil have been widely studied in field and laboratory settings. Nonmethane volatile organic compounds (VOCs) are also emitted from soil following a rain event and are evident from the characteristic smell of wet soil. Few studies have documented VOC emissions before and after soil rewetting. Soil emissions were studied using a dynamic flux chamber system purged with VOC‐free air, with identification and quantification of emissions performed by gas chromatography/mass spectrometry. All soils exhibited a rewetting‐induced pulse of VOC emissions, with VOC emissions 14 times higher (on average) in the few hours after rewetting compared to moist soils 2 days after rewetting. This VOC rewetting pulse mirrored the CO2 rewetting pulse (the so‐called “Birch Effect”) but was shorter in duration. Average VOC emissions were 5.0 ± 2.0% of CO2 emissions (molar C equivalent) and increased with increasing soil organic matter content (ρ = 0.40, ρ = 0.99 with one soil excluded). The amounts and types of VOCs varied with time since rewetting and across the five studied soil types, though acetone and small hydrocarbons were the dominant compounds emitted from all soils. Some of the VOCs emitted are likely important mediators of microbial activities and relevant to atmospheric chemical dynamics. Soil VOC emissions, similar to CO2 emissions, are strongly affected by rewetting events, and it is important to consider these rewetting dynamics when modeling soil and ecosystem VOC emissions and understand their relevance to terrestrial ecosystem functioning and atmospheric processes.

“…One day after both slurry applications, the C-VOC fluxes from the microcosms with slurries were higher than those in CS, except for the phenol emission, and, this increase lasted from one day for the acetone in SDPS up to 49 days for the DMS. Distinctive VOC emissions following the application of PS and DPS to soil have already been observed, especially for methanol fluxes that were induced after PS fertilization of soil compared with DPS fertilization (Potard et al, 2017). Interestingly, for all the VOCs measured, the emissions could be lower than those detected in CS (Fig.…”

“…It has previously been shown that soil organic amendments including digestates and N-mineral fertilization impact the VOC fluxes at the soil-atmosphere interface (Gray and Fierer, 2012;Seewald et al, 2010). Recently, using field monitoring, Potard et al (2017) observed that digested pig slurry amendments differently impacted the soil bacterial communities and reduced the C-VOC fluxes from soil to the atmosphere compared to the amendments of undigested pig slurry. Thus by modifying the microbial decomposer communities and/or the soil OM status, undigested and digested organic amendments impact the VOC emissions from soil.…”

“…The time scale of our experiment might not have been adapted and a short-term impact of the slurry application might have been visible by analyses performed within the first 30 days of incubation. Indeed, Potard et al (2017), based on field monitoring and next generation sequencing analysis, detected changes in soil microbial communities seven days after either PS or DPS application that were not detected anymore after 36 days. However, Pezzolla et al (2015) observed fluctuating trend in the C biomass of soil microorganisms up to 30 days following application of digestate from pig slurry to an agricultural soil in controlled conditions.…”

Production of biogas through anaerobic digestion of organic wastes should play an important role in sustainable development of energy supply, and the environmental effects of digestates have to be assessed. We investigated the effect of anaerobic digestion of pig slurry (PS) on the molecular quality of the digestate produced. The consequences of digested (DPS) and undigested PS use as organic soil fertilizer on soil microbial and biochemical properties and C-gas emissions (CO 2 and volatile organic compounds) were studied during a two-month incubation. PS and DPS differed in the amount of volatile organic compounds (VOCs) emitted, in their organic C and lignin contents but not in their active microbial composition. Application of both types of slurry to the soil immediately increased the content of soil dissolved organic carbon (DOC) compared to the control soil. The application of DPS induced few changes in the biochemical composition of soil organic matter compared to its raw material (PS) that increased the amount of phenolic compounds. After 60 days, both amended and control soils contained similar amounts of DOC, amended soils presenting a more diverse biochemical composition of their soil organic matter. Application of both slurries to soil triggered a succession of different active microbial communities, which could be attributed to the introduction of new microorganisms and the input of new labile organic carbon. Changes in fungal communities were stronger than those of bacteria and archaea; however, only slight differences were observed between the slurries. Different fluxes and emission dynamics of five VOCs (methanol, acetone, DMS, 2-pentanone and phenol) were observed during the incubation time following application of PS or DPS to soil while no differences in CO 2 emissions were observed. The present study calls for longterm field studies with VOC analyses as a promising tool to differentiate organic fertilization practices.

“…sample per site was sent to LABOCEA Comburg for standardised analyses (NF ISO or NFX norms) of total nitrogen and C/N (NF ISO 13878), granulometry (NFX 31107), organic matter (NF ISO 10694/14235), residual humidity (NF ISO 11465), cation exchange capacity (NF ISO 23470) and pH. In situ CO and volatile organic compounds (VOCs) emissions from soil in these three sites were measured four times during the BioBlitz (on the 18th afternoon, twice during the night from the 18th to the 19th and once on the 19th July morning) using dynamic gas sampling in canisters and later analysis on a micro gas chromatography (µGC) and proton transfer reaction mass spectrometer (PTR-MS), respectively (Potard et al 2017).…”

The Biological Field Station of Paimpont (Station Biologique de Paimpont, SBP), owned by the University of Rennes and located in the Brocéliande Forest of Brittany (France), has been hosting student scientific research and field trips during the last 60 years. The study area of the SBP is a landscape mosaic of 17 ha composed of gorse moors, forests, prairies, ponds and creeks. Land use has evolved over time. Historical surveys by students and researchers focused on insects and birds. With this study, we aimed to increase the range of taxa observations, document changes in species composition and landscape and provide a basis for interdisciplinary research perspectives. We gathered historical data, implemented an all-taxon biodiversity inventory (ATBI) in different habitats of the SBP study area, measured abiotic factors in the air, water and soil and performed a photographical landscape observation during the BioBlitz held in July 2017. During the 24 h BioBlitz, organised by the SBP and the EcoBio lab from the University of Rennes and the French National Center of Scientific Research (CNRS), different habitats were individually sampled. Seventy-seven experts, accompanied by 120 citizens and 12 young people participating in the European Volunteer Service, observed, identified and databased 660 species covering 5 kingdoms, 8 phyla, 21 classes, 90 orders and 247 families. In total, there were 1819 occurrences including records identified to higher taxon ranks, thereby adding one more kingdom and four more phyla. Historical data collection resulted in 1176 species and 4270 occurrences databased. We also recorded 13 climatic parameters, 10 soil parameters and 18 water parameters during the BioBlitz. Current habitats were mapped and socio-ecological landscape changes were assessed with a diachronic approach using 32 historical photographs and historical maps. The coupling of historical biodiversity data with new biotic and abiotic data and a photographic comparison of landscape changes allows an integrative understanding of how the SBP changed from agriculturally-used land to a managed natural area within the last 60 years. Hence, this BioBlitz represents an important holistic sampling of biodiversity for studies on trophic webs or on trophic interactions or on very diverse, but connected, habitats. The integration of social, biotic and abiotic data opens innovative research opportunities on the evolution of socio-ecosystems and landscapes.
