International audience ; The use of the ecosystem service notion by natural scientists is increasing since the Millenium Ecosystem Assessment report publication in 2005. This notion is generally associated with an economic assessment of the services that nature brings to humans, and thus it implies new relationships between science and public policy. It also questions the nature of scientific knowledge, since this knowledge must contribute more directly to the building of environmental policies. This article is focused on agricultural soils ; its aim is to study the ecosystem service approach impact on scientific production in soil science. A bibliographic study with the lexicometric software Iramuteq was made. Corpuses of scientific articles published from 1992 to 2012 were set up with the database Web of Science and they were analysed with Iramuteq. The results of the different corpus analysis were compared. So we observed that since the nineties, there have been important changes in research themes and relations between scientific disciplines within soil sciences. The main tendency in the study of agricultural soils is the expansion of ecological approaches. Articles which mention ecosystem service notion have distinctive characteristics : (i) modelling methods are not much used ; (ii) farming practices studies focus on their effects on soil conservation rather than on soil productivity and food production ; (iii) biological and ecological approaches are diversified and focused on micro- and macro-organisms communities and activities. Moreover, in the scientific literature we analyzed, ecological and biochemical processes that take place in agricultural soils are more and more precisely studied, but they are not linked with the provision of ecosystem services. As a conclusion, presently, the use of ecosystem service notion by researchers doesn’t change the knowledge nature produced on agricultural soils. ; Depuis la publication du rapport du Millenium Ecosystem Assessment (2005), on observe une utilisation ...
