Abstract : The SOERE-PRO (Observatory for monitoring and experimentation on agroecosystems fertilized with organic residues) is a long term field experiments network dedicated to the study of risks and benefits associated with organic residues usage. This network includes 4 main experimental sites in France equipped with sensors and monitoring material (La Mare, Reunion Island ; QualiAgro, Ile de France ; Colmar, Alsace ; EFELE, Bretagne). These sites are used to monitor closely the effects of organic residues application on the different compartments (soil, vegetation, water, air) of the agroecosystems. For some sites, this monitoring has been ongoing for more than 15 years. At SOERE-PRO Réunion, the following organic residues are applied to different plots of the sugarcane crop field: 1/ sludge pellets from Grand Prado waste water treatment plant, each year (BA); 2/ sludge compost from Grand Prado waste water treatment plant, every 4 years (CB); 3/ pig manure, each year (LP); 4/ poultry manure, every 4 years (LV). The effect of these organic residues is then compared to mineral-based fertilization (N, P, K). The field experiment was installed at " La Mare ", a location in Reunion Island, in November 2013. Sugarcane was planted on a total area of 1.2 hectares, which includes 30 plots. Each plot has an area of 294 m2, with dimensions 28m x 10m, and is organized in a randomized block design (5 blocks, 6 plots per block). At SOERE-PRO Reunion, instrumentation includes mainly: -TDR probes and tensiometers along the soil profile for soil water status monitoring -Lysimeters and soil water samplers for soil circulating water collection -Automated gas chambers, which close at regular intervals to measure gas fluxes in order to assess soil nitrous oxide (N2O) and carbon dioxide (CO2) emissions. -NH3 collectors (alpha badges) to estimate NH3 volatilisation
