Each site has three common treatments: a control (C), a compacted treatment (T), a compacted and decompacted treatment (D), and more specific ones, locally decompacted soil (P) at Azerailles 54, and, limed (A) and limed and compacted (CA) at Clermont en Argonne 55. Each treatment plot of 0.25ha is replicated three times (3 blocks). Azerailles site was installed in spring 2007 and Clermont in spring 2008. Since that time monitoring occured for: -mesoclimate: rainfall, air temperature, relative humidity, bulk deposition (continuous recording) - soil climate: soil moisture (TDR Trase system (5 replicates at 15 and 60 cm depth) in one replicate of C and T (recorded each four hours) - water table: 2 piezometers in each replicate of treatments (Divers hourly recorded); monthly sampling using specific devices for Redox problems - weakly fixed soil water: cup lysimeters inserted at 15 and 60 cm depth (4 replicates in one block for C and T treatments) + teatments A and CA at Clermont en Argonne. Automate for constant vacuum at 700hP. Monthly collection for chemical analysis - soil gas: specific captors installed at 5, 10, 20, 35, 50 and 70 cm depth in each C and T treatments of the 3 blocks in the 2 sites. Monthly collection for chemical analysis (N, CO2, CH4, N2O, O2) -soil solid phase: soil morphology, soils physics, chemistry and biology (pro parte) were initialy described. Soil physical parameters (strengh, bulk density, hydraulic conductivity, swelling/shrinkage, porosity...), chemistry (C, N, exchangeable cations, P) and biology (earthworms) are perediodicaly investigated (each year for physics; 2/3 years for chemistry and biology). vegetation: both understorey and oak plantation were annually observed soil biology: earthworms are periodically observed

The site of EFELE (Effluents d’Elevage et Environnement) is part of the french network labeled as SOERE PRO. The objectives of EFELE are the same as QualiAgro and Colmar sites : the aim of the project is to characterize the long term effects of organic products applications on soil properties and to quantify their effects on water and air quality. The experimental site was initiated in 2012 and is located in Brittany, at Le Rheu. The soil is a loamy soil (neoluvisol à luvisol/redoxisol). The field is managed with a maize/ wheat crop rotation, and white mustard is sown after the wheat to cover the soil during the intercropping period. Two trials are studied at EFELE site : - A first trial named « PROs » is structured as a complete randomized block design with 4 replicates. The effects of 5 typical animal wastes are compared to control treatments : i) cattle farmyard manure and composted pig manure are applied every 2 years before maize sowing, and ii) layers manure, pig slurry and a digestate obtained after pig slurry digestion are applied in spring, on wheat vegetation at early spring or just before maize sowing. The rates of application range from 50 t ha-1 for cattle manure, 25 t ha-1 for composted pig manure, 20-25 t ha-1 for the slurry and the digestate and 3 t ha-1 for layers manure, - A second trial named « TS/MO » is structured as a band trial with 3 replicates. The objectives of this trial are to study the effects of cattle farmyard manure on soil properties under conventional tillage and reduced tillage. The meteorological data are monitored on the site, and 7 experimental plots are equipped with TDR probes (TRASE system), tensiometers (UMS T4e) and temperature probes placed at the depth of 13, 40, 60, 80 and 110 cm. Data are collected at a hourly time step. 10 plots are also equipped with wick lysimeters (0.25 x 0.50 m) placed at the depth of 40 and 90 cm. The monitoring of N2O and CO2 emission is done by a set of 6 automatics chambers. The soil surface layer (0-25 cm) is sampled every year before the animal wastes application, to characterize the evolution of the physical, biological and chemical properties. Soil, plant and animal wastes samples are kept in collection.

The site of Colmar is part of the French national network SOERE PRO (System of Observation and Experimentation for Environmental Research on Organic Residue Recycling). The objectives of the site of Colmar are to characterize the agronomic value of organic residues and their environmental impacts, in a long-term field experiment. It has been initiated in 2001 (INRA / SMRA68 / ADEME / Agence de l’Eau Rhin-Meuse partnership). The experimental site is located in Colmar (Alsace, France) with a continental climate. The soil is a calcisoil (surface layer: 24% clay, 69% silt, 7% sand / 2.4 % organic matter / pH 8.3). The trial is composed of 60 plots of 90 m² (10 m x 9 m) on 2.2 hectares with 4 replicate blocks of 6 organic treatments randomly distributed within each block: Urban sewage sludge, Composted sewage sludge, Biowaste compost, Farmyard manure, Composted Farmyard manure, Control without organic amendment. The organic amendments are spread every 2 years on the same nitrogen rate of 170 kg/ha. The different treatments received 2 levels of additional mineral fertilizer: without or optimum mineral fertilization. The crops rotation is corn maize / winter wheat / sugar beet / malting barley. Site and plots are equipped for continuous monitoring of meteorological data, soil humidity, water tension and temperature. One plot of each treatment is equipped with wick lysimeters to a depth of 0.45 m. Since 2009, six large lysimeters (4m² and 1m deep, bare soil) complete the field experiment, with 2 replicates of 3 organic treatments: Urban sewage sludge, Composted sewage sludge and Control without organic amendment. They are also equipped to measure the hydrodynamic balance: soil humidity, water tension, temperature, volume of leachate. A Large set of variables mainly including nutrients and pollutants (trace elements, PAH, PCB), are monitored on different compartments of the agro-system: organic amendments physico-chemical and biochemical characteristics, soils analytical characteristics per layer, crop yields, plants quality, rainwater chemical composition, leachate, microbial biomass and activities. Data will be stored in a common database specifically developed for the SOERE PRO network and connected with other SOERE. Soils, organic amendments and plants samples are kept in collection and available for further measurements.

The Estrées-Mons platform is dedicated to arable crops. It evaluates the effect of agricultural practices on C and N cycles in the soil-plant system and their interaction. Nitrate leaching, SOM evolution and GHG emissions (CO2, N2O) are monitored according to level of N intensification, crop residues export, soil tillage and legume frequency. The key issue is to understand how the wide variation in C and N inputs affects C and N cycles in more or less intensified systems.

The Lusignan platform is dedicated to temporary grassland. It has been designed to increase our understanding of the effects of management of mixed arable crops / grasslands systems on the environmental outputs. The main scientific issue concerns the effects of grassland duration and management on SOM dynamics (quantity and composition), GHG emissions (CO2, N2O), nutrient lixiviation and functional biodiversity.

The site of Montiers, localized at the boundaries between Meuse and Haute-Marne departments, North-East of France, has a large surface area (143 ha). It comprises two soil successions (toposequence) and the climate, stand conditions (age, species, forest management) are equivalent on all the surface of the site. The facility comprises three biogeochemical stations of 10 000 m2 each and one flux tower above forest canopy (45 m-high) settled along a soil succession representative of soils of the region. The three stations include four substations of which three are strongly equipped and one is free for future experimentations. Each equipped substation comprises lysimeters at different soil depths (litter, -10 cm, -30 cm, -60 cm and -90 cm; 3 replicates in general), tensio-lysimeters (-10 cm, -30 cm, -60 cm, -90 cm and -120 cm; 3 replicates in general) and temperature and moisture probes at different soil depths (-10 cm, -30 cm, -60 cm and -90 cm; 4 replicates), litterbags (6 replicates), stemflows (6 replicates), gutters (4 replicates). These stations allow to follow-up on the long term the flows of water, and major (Ca, Mg, K, Na, P, Fe, Mn, Si, Al, S, C, N) and trace (Cl, Se, B, I, Cs) elements between the different compartments (soil, tree, atmosphere) of a beech forest. Each station is settled on a different soil type, i.e., alocrisol, calci-brunisol, rendosol thus allowing to assess the impact of the soil type on biogeochemical cycles and on tree growth. The flux tower is equipped with a Eddy Covariance system (CO2, H2O, and sensible heat) and a complete set of sensors recording the aerial and edaphic meterological conditions, the phenology and the canopy status. The data from flux tower are available on demand. The forest mainly consists in a beech timber of about 50 years: dominant species and forestry in the region. The effect of the soil on the biogeochemical and biological functioning of this beech forest is dealt with a very integrated approach (ecophysiology, microbiology, soil science and biogeochemistry). In addition, the flux tower permits to measure, at various levels of the canopy and above, meteorological parameters (temperature, radiation, and precipitation), the gaseous exchanges and the particular deposits.
