Soil DNA evidence for altered microbial diversity after long-term application of municipal wastewater

2010

International audience; Water resources constitute a social, agricultural and economic problem in most countries of the southern Mediterranean Basin. Alternative strategies have been developed such as the reuse of municipal wastewater for irrigation in agriculture. Despite numerous advantages for soil fertility and crop productivity, recycling wastewater in soils also has several ecotoxicological and sanitary problems. Few investigations have assessed the risk by evaluating the impact of wastewater irrigation on soil microbes. Here, we report for the first time the short- and long-term effects of treated municipal wastewater irrigation on the density and genetic structure of bacterial and f…

Soil erosion processes in European vineyards: A qualitative comparison of rainfall simulation measurements in Germany, Spain and France

2016

Small portable rainfall simulators are considered a useful tool to analyze soil erosion processes in cultivated lands. European research groups in Spain (Valencia, Málaga, Lleida, Madrid and La Rioja), France (Reims) and Germany (Trier) have used different rainfall simulators (varying in drop size distribution and fall velocities, kinetic energy, plot forms and sizes, and field of application) to study soil loss, surface flow, runoff and infiltration coefficients in different experimental plots (Valencia, Montes de Málaga, Penedès, Campo Real and La Rioja in Spain, Champagne in France and Mosel-Ruwer valley in Germany). The measurements and experiments developed by these research teams give…

Caractérisation de la dynamique de l'eau et des intrants à la parcelle: comparaison de dispositifs

2017

Notre système d’agriculture intensif cause une pollution accrue des eaux souterraines par lixiviationdes traitements appliqués sur les parcelles. Notamment l’utilisation des engrais azotés est, depuis 65 ans, enconstante augmentation. Cependant, cet azote rejoint les nappes phréatiques, rendant l’eau impropre à laconsommation. Le diagnostic de cette pollution azotée est donc un enjeu majeur de santé publique et est lié àdes conséquences économiques importantes car une nappe polluée devra être traitée et une autre nappeservira à la consommation, ce qui demande de nouvelles installations. Des instruments ont été créés pourprélever l’eau qui lixivie sous les parcelles agricoles afin d’analyser…
