The long-term experiment PROspective site is located at the Colmar Experimental Centre of the French National Research Institute for Agriculture, Food and Environment (INRAE), in Colmar (Haut-Rhin, France; 48◦03’33’’ N, 7◦19’42’’ E, altitude 200 m). It is positioned on a silt–silt clayey calcisol soil. The upper horizon includes a plough layer (i.e., topsoil), which is carbonated. The climate is semicontinental, with a mean annual precipitation of 559 mm received mostly between May and October and an average annual air temperature of 11.3 ◦C. It is cropped with a rotation of maize, winter wheat, sugar beet and barley. Each organic waste product application are made before maize or sugar beat every 2 years most often in February, at doses equivalent to 170 kg N ha−1 (Michaud et al. 2021, Chen et al. 2022). // The figure in attached file presents the experimental plan of the PROspective long-term field experiment. The 2-ha field experiment is divided into 2 sub-devices “With_N” and “Without_N” including 24 plots of 10 m × 9 m in 4 blocks of replicates and a fifth block devoted to the following of the nitrogen dynamic with bare plots or control plots without mineral fertilization. The following organic waste products are randomly distributed within each block: Sewage sludge (SLU), Co-compost of sewage sludge with green waste and wood chips (GWS), Co-compost of the home-sorted fermentable fraction of municipal solid waste and green waste, also called biowaste compost (BIOW), Farmyard manure from a dairy farm (FYM), Compost of farmyard manure (CFYM), No organic amendment (control, or CN). // From 2000 to 2019, two phases were carried out in the PROspective long-term experiment as presented in the attached table, with the treatments randomly distributed in the 2 sub-devices, as follows: In the sub-device “with_N” in 2000–2019 on all plots of the blocks 1 to 4, additional mineral N fertilization was applied at doses between 0 and 170 kg N ha−1. In the sub-device “without_N”, in 2000-2014 on all plots no additional mineral N fertilization was applied; in 2015-2019 additional biowaste digestate (DIG) was applied at doses between 0 and 170 kg N ha−1.
