Peaks of in situ N2O emissions are influenced by N2O producing and reducing microbial communities across arable soils

2018

International audience; Introduction Agriculture is the main source of terrestrial N2O emissions, a potent greenhouse gas and the main cause of ozone depletion ((Hu et al., 2015). The reduction of N2O into N2 by microorganisms carrying the nitrous oxide reductase gene (nosZ) is the only known biological process eliminating this greenhouse gas. Recent studies showed that a previously unknown clade of N2O-reducers (nosZII) was related to the potential capacity of the soil to act as a N2O sink (see Hallin et al., 2017 and references therein). However little is known about how this group responds to different agricultural practices. Here, we investigated how N2O-producers and N2O-reducers were …

N2O emission in maize-crops fertilized with pig slurry, matured pig manure or ammonium nitrate in Brittany

2008

International audience; N2O is a potent greenhouse gas and solutions have to be sought to reduce its emission from agriculture. This work evaluates N2O emission from maize-crop (Zea mays) fields submitted to different organic or mineral fertilizers (pig slurry, matured pig manure or ammonium nitrate) in Brittany (France). N2O emission was evaluated along a year in two experimental sites receiving 110 or 180 kg N ha−1 as ammonium nitrate or pig slurry and 180 or 132 kg N ha−1 as ammonium nitrate or matured pig manure at Champ Noel and Le Rheu experimental plots, respectively. N2O emission was evaluated by interpolation method of periodic fluxes on the field scale and by simulation with NOE a…

Innovazione di processo nel comparto dell'uva da tavola: due produzioni nello stesso anno adottando la tipologia produttiva del fuori suolo

2014

Tests were conducted in 2011; was studied the chance to develop two production cycles in the same year. For both cycles were used plants set up in 2010. The two production cycles were conducted during "winter-spring" and the second during the "summer-autumn". For the second cycle were used two different types of plants. Production levels reached in the second cycle were satisfying in terms of quantity and quality for both types of plants. Cumulative production amount to 70 tons/ha.

Habilitation Thesis

2004

This habilitation thesis presents a synthesis of my research activities during the last eight years. I have distinguished, one the one hand, researches concerning rovibrational spectroscopy in a singlet electronic state (Part III) and, on the other hand, those concerning rovibronic spectroscopy in a degenerate electronic state (Part IV).

Assessing the territorial influence of an Iberian worship site. The chemical characterisation of the terracotta from the Iron Age sanctuary of La Ser…

2017

This paper presents the study of the prestigious terracotta votive figurines from the Iberian Iron Age sanctuary of La Serreta (Alicante province, Spain) composed of 174 items. Portable X-ray fluorescence (PXRF) was used to identify elemental markers that permit us to observe the differences between local and non-local terracotta figurines and furthermore to evaluate the geographical influence of the La Serreta sanctuary using Principal Component Analysis (PCA). The Partial Least Squares Discriminant Analysis (PLSDA) statistical method was also used to classify the figurines of uncertain geographical origin. The resulting groups were related to typological and stylistic groups of figurines …

Legume inoculants to reduce soil emissions of nitrous oxide

2012

Nitrous oxide (N2O) is a potent greenhouse gas involved in depletion of the ozone layer and mainly arising from the soil and from agricultural activities. Within this framework, INRA teams inoculated soybean plants with natural strains of Rhizobia bacteria. Convincing results regarding the consumption of N2O greenhouse gases were obtained.
