New Particle Formation (NPF) is a major source of ultrafine particles that affect both air quality and climate. Despite emissions from agricultural activities having a strong potential to lead to NPF, little is known about NPF within agricultural environments. The aim of the present study was to investigate the occurrence of NPF events at an agricultural site, and any potential relationship between agricultural emissions and NPF events. A field campaign was conducted for 3 months at the FR-Gri-ICOS site (France), at an experimental farm 25 km west of Paris city centre.

Soil is a potential reservoir of human pathogens and a possible source of contamination of animals, crops and water. In order to study the distribution of Listeria monocytogenes in French soils, a real-time PCR TaqMan assay targeting the phosphoribosylpyrophosphate synthetase (prs) gene of L. monocytogenes was developed for the specific detection and quantification of this bacterium within a collection of 1315 soil DNAs originated from the French Soil Quality Monitoring Network. The prs real-time PCR TaqMan assay was specific for L. monocytogenes and could quantify accurately down to 104L. monocytogenes per gram of dry soil. Among the 1315 soil DNAs, prs was not detected. This suggested that the level of L. monocytogenes in French soils is generally less than 104L. monocytogenes per gram of dry soil. In order to confirm this hypothesis, we investigated the occurrence of L. monocytogenes in samples collected in the Burgundy region by culture-based and molecular detection methods on the same samples. By using cultivation-based detection, 17% of samples were positive for the presence of L. monocytogenes while only 2% were found positive by the molecular detection method. L. monocytogenes was repeatedly isolated from cow pasture soils but not from cultivated soils, meadows or forest soils. Isolates were grouped in the serovar 1/2a or 3a and 4b or 4d or 4e. Taken as a whole, molecular detection results globally demonstrate that the level of L. monocytogenes in French soils does not exceed 104CFU per gram of dry soil. However, in comparison with culture-based method, PCR-based detection underestimates the occurrence of L. monocytogenes in soils. Soil sampling procedure also appears critical and may also lead to the underestimation of the incidence of L. monocytogenes.

Understanding the relationship between soil organic carbon (SOC) storage and nitrous oxide (N2O) fluxes is crucial for sustainable land management. In this study, we examined this relationship in different cropping systems, including annual cropping systems with a legacy of varying durations (3 versus 6 years) of grasslands and continuous grassland. The aim was to investigate (1) the effect of contrasting management practices on SOC storage and N2O emissions under field conditions and (2) to elucidate the drivers of N2O emissions under controlled conditions. Our findings showed that despite the influence of management practices on SOC stocks, no trade-off was observed between SOC storage at two different depths (10 and 30 cm) and N2O emissions. Furthermore, we found that SOC chemical signature, soil physical characteristics, and denitrifier activity, rather than SOC content and denitrifier abundances, were the primary factors determining N2O emission potential. It is interesting to note that although functional gene abundances were related to denitrifier activities, they did not show a direct correlation with N2O emissions. This suggests that environmental factors and microbial activity play a more substantial role in determining N2O emissions than denitrifier abundances. The inclusion of temporary grassland in a crop rotation had a positive impact on SOC stocks, either by improving or maintaining their levels. However, as a trade-off the introduction of temporary grassland also led to higher N2O emissions. These increased emissions were not directly associated with the amount of SOC stored in soil but rather with changes in soil physical and chemical conditions.

Process-based models are useful for assessing the impact of changing management practices and climate on yields and greenhouse gas (GHG) emissions from agricultural systems such as grasslands. They can be used to construct national GHG inventories using a Tier 3 approach. However, accurate simulations of nitrous oxide (N2O) fluxes remain challenging. Models are limited by our understanding of soil-plant-microbe interactions and the impact of uncertainty in measured input parameters on simulated outputs. To improve model performance, thorough evaluations against in situ measurements are needed. Experimental data of N2O emissions under two management practices (control with typical fertilization versus increased clover and no fertilization) were acquired in a Swiss field experiment. We conducted a multimodel evaluation with three commonly used biogeochemical models (DayCent in two variants, PaSim, APSIM in two variants) comparing four years of data. DayCent was the most accurate model for simulating N2O fluxes on annual timescales, while APSIM was most accurate for daily N2O fluxes. The multimodel ensemble average reduced the error in estimated annual fluxes by 41% compared to an estimate using the Intergovernmental Panel on Climate Change (IPCC)-derived method for the Swiss agricultural GHG inventory (IPCC-Swiss), but individual models were not systematically more accurate than IPCC-Swiss. The model ensemble overestimated the N2O mitigation effect of the clover-based treatment (measured: 39–45%; ensemble: 52–57%) but was more accurate than IPCC-Swiss (IPCC-Swiss: 72–81%). These results suggest that multimodel ensembles are valuable for estimating the impact of climate and management on N2O emissions.
