AB Long-term bare fallow (LTBF) experiments with historical sample archives offer uniqueopportunities to study long-term impacts of anthropogenic activities on mineral soil fractions.In natural agro- and ecosystems, such impacts are often masked by organic matter due to itsbuffering action and rapid turnover. The 42-plot LTBF trial of INRA (Institut National de la RechercheAgronomique) started in Versailles (France) in 1928 to assess the impacts of prolonged application offertilizers and amendments on the composition and properties of loamy soils. Here, we establishedgeochemical budgets of major and trace elements on surface samples from 1929 and 2014 for fourgroups of treatments relevant for developed soil processes. We considered accompanying effects ofsoil compaction or decompaction due to changing physicochemical conditions over 85 years. Elementlosses from the surface horizon were quantified via fertilization-induced or -amplified soil processes:clay leaching favored by Na- or K-based fertilization, and lixiviation of major and trace elementsin acidic or alkaline soil conditions. Enhanced mineral weathering was shown for acidified andnonamended plots. Conclusions on trace metal migration were confirmed by selected analyses onsubsurface horizons. Additional information was provided on specific element inputs via fertilizersand/or diffuse inputs via atmospheric deposition
