    Constructed wetlands and ponds (CWs) are installed to trap suspended material and particulate phosphorus (P) in agricultural runoff. This study investigated whether the P speciation and P sorption capacity of source soils differ from those of CW sediments and whether drying of dredged sediment changes its characteristics. Samples collected from five agricultural CW sites in south-west Finland, two with chemical-aided (aluminium chloride and ferric sulphate) P precipitation and all representing fine-textured mineral soils, were analysed for various P plant availability indices. Clay contents of the CW sediments were much higher than in catchment soils, likely because of selective erosion. All CW sediments were characterised by similar total P content but clearly higher content of anion exchange resin-extractable P in fresh sediments than the source soils. In general, sediment content of NH4F-extractable (aluminium (Al)-associated) P was significantly lower and NaOH-extractable (iron (Fe)-associated) significantly higher than in source soils. Reduced conditions, conducive to mobilisation of Fe-associated P, were observed in all CWs. Accumulation of sulphur (S) in sediments and a pH decline of up to two units upon drying suggested presence of Fe sulphides. Drying also increased oxalate-extractable Al and Fe (hydr)oxide content by 9–47%, resulting in lower degree of P saturation. These results indicate that dredged CW sediments differ greatly in their P retention characteristics from their parent soils. Returning CW sediments to fields is likely to decrease the amount of readily available P for crop uptake. Peer reviewed

    [Departement_IRSTEA]Ecotechnologies [TR1_IRSTEA]TED; From a global perspective, agricultural ecosystems are challenged by a requirement to produce more outputs with lower inputs, simultaneously to meet the demand for more food and reduce the global environmental impact of agriculture. A key task is to develop and share new ecological concepts of agriculture as a means to improve nutrient recycling, particularly of nitrogen and phosphorus. This paper explores opportunities to achieve this use of new agronomic tools, novel organic fertilizer products and innovative distribution networks. It draws on the results of recent projects in Europe that have developed and tested novel manure processing technologies as well as approaches to integrate nutrient management at local to regional scales.

    Anthropogenic inputs of trace elements (TE) into soils constitute a major public and environmental health problem. Bioavailability of TE is strongly related to the soil physicochemical parameters and thus to the ecosystem type. In order to test whether soil parameters influence the response of the bacterial community to TE pollution, we collected soil samples across contrasting ecosystems (hardwood, coniferous and hydromorphic soils), which have been contaminated in TE and especially lead (Pb) over several decades due to nearby industrial smelting activities. Bacterial community composition was analysed using high throughput amplicon sequencing and compared to the soil physicochemical parameters. Multivariate analyses of the pedological and biological data revealed that the bacterial community composition was affected by ecosystem type in the first place. An influence of the contamination level was also evidenced within each ecosystem. Despite the important variability in bacterial community structure, we found that specific bacterial groups such as γ-Proteobacteria, Verrucomicrobia and Chlamydiae showed a consistent response to Pb content across contrasting ecosystems. Verrucomicrobia were less abundant at high contamination level whereas Chlamydiae and γ-Proteobacteria were more abundant. We conclude that such groups and ratio's thereof can be considered as relevant bioindicators of Pb contamination.

    International audience; Time-saving, low-cost analyses of soil contamination are required to ensure fast and efficient pollution removal and remedial operations. In this work, laser-induced breakdown spectroscopy (LIBS) has been successfully applied to in situ analyses of polluted soils, providing direct semi-quantitative information about the extent of pollution. A field campaign has been carried out in Brittany (France) on a site presenting high levels of heavy metal concentrations. Results on iron as a major component as well as on lead and copper as minor components are reported. Soil samples were dried and prepared as pressed pellets to minimize the effects of moisture and density on the results. LIBS analyses were performed with a Nd:YAG laser operating at 1064 nm, 60 mJ per 10 ns pulse, at a repetition rate of 10 Hz with a diameter of 500 lm on the sample surface. Good correlations were obtained between the LIBS signals and the values of concentrations deduced from inductively coupled plasma atomic emission spectroscopy (ICP-AES). This result proves that LIBS is an efficient method for optimizing sampling operations. Indeed, ''LIBS maps'' were established directly on-site, providing valuable assistance in optimizing the selection of the most relevant samples for future expensive and time-consuming laboratory analysis and avoiding useless analyses of very similar samples. Finally, it is emphasized that in situ LIBS is not described here as an alternative quantitative analytical method to the usual laboratory measurements but simply as an efficient time-saving tool to optimize sampling operations and to drastically reduce the number of soil samples to be analyzed, thus reducing costs. The detection limits of 200 ppm for lead and 80 ppm for copper reported here are compatible with the thresholds of toxicity; thus, this in situ LIBS campaign was fully validated for these two elements. Consequently, further experiments are planned to extend this study to other chemical elements and other matrices of soils.

     ; A pedo-geochemical survey was carried out in the Nord-Pas de Calais region (France) on soils developed in sedimentary materials to estimate their baseline geochemistry and the effect of selected factors on it. Total concentrations of Al, Fe and 18 trace elements, as well as common soil characteristics, were determined in samples from 271 surface and 487 deep horizons developed in 22 sedimentary rocks and superficial deposits. Compared with the upper continental crust, the parent materials are enriched with most of the trace elements, particularly with As, Cd, Sb and Se, and are impoverished in Cu. Calcareous rocks from the Carboniferous, Cretaceous and Jurassic eras are often enriched in Cd. Correlation analysis shows that the least mobile (i.e. ionic potential (Z/r) ranges from 3 to 7) geogenic elements (Bi, Co, Cr, Cu, In, Ni, Pb, Sn, Tl, V, Zn) are associated with the < 2 μm fraction (which we define as “lutum”). More mobile elements (As, Cd, Hg, Mn, Mo, Sb, Se) are less strongly associated with this fraction. Cadmium is particularly associated with Mn. Topsoils are enriched with all the trace elements examined, except Co, Cr and Ni, probably because of anthropogenic contamination. The amount of Pb introduced into the soils of the entire region (12 450 km2) by human diffuse contamination is estimated to be 45 000 metric tonnes. Organic matter seems to act as a sink for numerous exogenous trace elements. The distribution of [trace element]/([Al] or [Fe]) in the deep soil horizons from Nord-Pas de Calais gives the background contents for soils developed from most sedimentary materials from the Brussels–London and the Parisian basins.

    Included in the 2nd tier of a site specific risk assessment that is being carried out in an abandoned uranium mine (Cunha Baixa uranium mine, Central Portugal), fatty acids biomarkers and sterols were analyzed to assess the impact of soil contamination with metals and radionuclides in the structure of the microbial community in seven sampling sites located at different distances from the mine. Surface soil samples were collected in those sampling sites in the four different seasons of the year. Principal component analysis (PCA) was performed on fatty acid biomarkers and sterols. Subsequently PCA scores obtained for both components were used to test the effect of sites and seasons, on soil samples collected in the Cunha Baixa uranium mine, through bi-factorial ANOVAs. Through PCA analysis, two distinct groups were set apart along the first two components. One group included sites at a great distance from the mine which were negatively correlated with higher contents of iC15:0 and iC17:0, both indicators of Gram-positive bacteria, as well as with ergosterol, cholestanol and cholesterol. The second group, in turn, was composed of the sampling sites most impacted by ore exploration, in situ leaching of poor ore, and spread of sludge from the effluent treatment pond. These sites were positively correlated with higher levels of iC16:0 (Gram-positive bacteria indicator), cyC17:0 (generally common in gram negative bacteria) and C18:0 and C17:0 biomarkers of non-specific bacteria. The profile of fatty acids obtained in the sampling sites revealed variable predominance of groups of bacteria which are a clear indication of differences in the soil microbial communities that are directly related to the environmental conditions prevailing in the uranium mine area. published

    Processing of organic residues may affect plant-availability of phosphorus (P) and thus the potential to recycle the nutrient, i.e., recyclability, but empirical evidence in the field is lacking. In field experiments in clay and silt loam soils with low available P, impact on P recyclability by cattle manure and sewage sludge processing methods (composting, anaerobic digestion, lime-stabilization, acid-oxidizer) and three application rates were assessed. Synthetic nitrogen (N) and potassium (K) fertilizers were supplied in surplus and NPK served as a reference. The differences in plant response were small at relevant application rates and not consistently explained by solubility of fertilizer P. Least P was required in composted manure for the same P uptake in silt loam, and composting was beneficial to plant response in clay as well. Lime-stabilization of sewage sludge had an adverse effect on P uptake in silt loam. Increasing application rates of sewage sludge hardly enhanced but did not lower P uptake or yield even at an excessive rate. Soil water-extractable P in the autumn liable to leaching was increased by NPK only. In clay soil, sewage sludges performed better than manures obviously due to anaerobic conditions caused by high precipitation, but in silt loam the contrary was the case. In conclusion, the availability of P in processed residues is more susceptible to weather and soil variables than in synthetic fertilizer. P fertilization benefits in cereal cropping in current north European conditions appear to be generally small. Peer reviewed

    AbstractDenitrification is mediated by microbial, and physicochemical, processes leading to nitrogen loss via N2O and N2 emissions. Soil pH regulates the reduction of N2O to N2, however, it can also affect microbial community composition and functional potential. Here we simultaneously test the link between pH, community composition, and the N2O emission ratio (N2O/(NO + N2O + N2)) in 13 temperate pasture soils. Physicochemical analysis, gas kinetics, 16S rRNA amplicon sequencing, metagenomic and quantitative PCR (of denitrifier genes: nirS, nirK, nosZI and nosZII) analysis were carried out to characterize each soil. We found strong evidence linking pH to both N2O emission ratio and community changes. Soil pH was negatively associated with N2O emission ratio, while being positively associated with both community diversity and total denitrification gene (nir & nos) abundance. Abundance of nosZII was positively linked to pH, and negatively linked to N2O emissions. Our results confirm that pH imposes a general selective pressure on the entire community and that this results in changes in emission potential. Our data also support the general model that with increased microbial diversity efficiency increases, demonstrated in this study with lowered N2O emission ratio through more efficient conversion of N2O to N2.

    Summary An important goal of the European Commission-funded ECOGEN project is to develop a computer-based decision support system (DSS) for the assessment of economic and ecological impacts of using genetically modified crops. In ecological impact assessment, special emphasis is put on soil biology and estimating soil quality from the observed biological parameters. Methodologically, we have addressed this goal using model-based DSS, taking the approach of qualitative multi-attribute modelling. The approach is based on developing various hierarchical multi-attribute models that consist of qualitative attributes and utility (aggregation) functions, represented by decision rules. The model presented in this paper assesses the impact of cropping systems on soil quality and can subsequently be used to assess crop management options. It was developed as a collaboration between ECOGEN soil experts and decision analysts, and consists of 34 attributes, hierarchically structured into eight levels. There are 21 input attributes, most of which measure the richness and biomass of representative soil organisms. The assessment of soil quality is based on two main indicators: (1) soil diversity (assessed through microfauna, mesofauna and macrofauna richness) and (2) soil functioning (in terms of leaching, comminution, mineralisation and plant growth). In the paper, we address the methodological aspects of the model and its development, and describe the components of the model (attributes, value scales, decision rules and weights). We present initial results of its application to the assessment of crop management on soil quality in the case of using conventional and Bacillus thuringiensis (Bt)-maize at three field sites in France and Denmark. Our finding was that soil quality was unaffected even though several input attributes had changed. We also analyse the sensitivity of the model and discuss its current and potential contribution to soil quality management. The model is operational (available through a web page) and can be used for the assessment, comparison and analysis of realistic management scenarios. Furthermore, it provides an effective means of synthesising a lot of data, encoding knowledge about soil-quality factors, supporting communication among experts, answering ‘what-if’ and ‘so-what’ questions, and supporting the evaluation of new agricultural practices.

    Abstract Contamination of the environment by radionuclides is usually estimated using soil and grass sampling. However, radionuclides are often not homogeneously distributed in soils. In the alpine Mercantour region (Western Alps, France) a large heterogeneity in Chernobyl 137 Cs deposition has been previously observed. Here we report additional 137 Cs results together with new 90 Sr and Pu data for soil, grass, milk, and cheese samples. The results show that radioisotopes from nuclear weapons tests fallout are more homogeneously distributed than Chernobyl 137 Cs. Further, we observe that the 137 Cs and 90 Sr contents are less variable in milk samples than in grass or soil samples. This can be attributed to the homogenization effect of cow vagrancy during grazing. Hence milk seems to be a more robust sample than soil or grass to evaluate the extent of contamination on a regional scale. We explore this idea by comparing own unpublished 90 Sr results and 90 Sr results from the literature to establish the relationship between altitude of grazing and contamination of soil and milk for Western Europe. There is a significant positive correlation between soil contamination and altitude and an even closer correlation between milk 90 Sr activity ( A ) and altitude ( h ): A = A 0 + e k · h where A 0 is the expected activity of milk sampled at sea level ( A 0 = 0.064 ± 0.014 Bq g −1 Ca) and h is the altitude of grazing, k being a constant ( k = 0.95 × 10 −3 ± 0.11 × 10 −3 m −1 Bq g −1 Ca). The fact that there is less scattering in the relationship for the 90 Sr milk -altitude than for 90 Sr soil -altitude suggests, again, that milk is a well-suited sample for environmental survey. The relationship between the altitude of grazing and the 90 Sr content of milk and cheese can also be used to assess the authenticity of dairy products.

    Constructed wetlands and ponds (CWs) are installed to trap suspended material and particulate phosphorus (P) in agricultural runoff. This study investigated whether the P speciation and P sorption capacity of source soils differ from those of CW sediments and whether drying of dredged sediment changes its characteristics. Samples collected from five agricultural CW sites in south-west Finland, two with chemical-aided (aluminium chloride and ferric sulphate) P precipitation and all representing fine-textured mineral soils, were analysed for various P plant availability indices. Clay contents of the CW sediments were much higher than in catchment soils, likely because of selective erosion. All CW sediments were characterised by similar total P content but clearly higher content of anion exchange resin-extractable P in fresh sediments than the source soils. In general, sediment content of NH4F-extractable (aluminium (Al)-associated) P was significantly lower and NaOH-extractable (iron (Fe)-associated) significantly higher than in source soils. Reduced conditions, conducive to mobilisation of Fe-associated P, were observed in all CWs. Accumulation of sulphur (S) in sediments and a pH decline of up to two units upon drying suggested presence of Fe sulphides. Drying also increased oxalate-extractable Al and Fe (hydr)oxide content by 9–47%, resulting in lower degree of P saturation. These results indicate that dredged CW sediments differ greatly in their P retention characteristics from their parent soils. Returning CW sediments to fields is likely to decrease the amount of readily available P for crop uptake. Peer reviewed

    [Departement_IRSTEA]Ecotechnologies [TR1_IRSTEA]TED; From a global perspective, agricultural ecosystems are challenged by a requirement to produce more outputs with lower inputs, simultaneously to meet the demand for more food and reduce the global environmental impact of agriculture. A key task is to develop and share new ecological concepts of agriculture as a means to improve nutrient recycling, particularly of nitrogen and phosphorus. This paper explores opportunities to achieve this use of new agronomic tools, novel organic fertilizer products and innovative distribution networks. It draws on the results of recent projects in Europe that have developed and tested novel manure processing technologies as well as approaches to integrate nutrient management at local to regional scales.
