This article present observational and experimental data describing a range of biotic and abiotic parameters that can be related to ecosystem services under contrasted types of crop management: conventional, conservation and organic agricultures. Ninety fields, either cultivated with winter wheat or fava bean, located in Southwestern France, near Toulouse, were monitored for two growing seasons (2014-2016). The dataset encompass data about crop pests (aphids, grain borer, bean beetles, slugs), crop pest natural enemies (hoverflies, parasitoids, predators), soil sensitivity to erosion, crop productivity, pathogenic fungal infection and root colonization by mycorrhiza. This article present detailed protocols applied for each measurement and data collected to describe the context of each field: soil structure, landscape and crop management indicators. The data presented here can be found in Portail Data INRA repository (DOI: 10.15454/KEW1GK) and were exhaustively used and discussed in the research article Conservation agriculture as a promising trade-off between conventional and organic agriculture in bundling ecosystem services [1].
