Human activities worldwide menace beneficial soil ecosystem services, but long-term anthropogenic impacts on properties and processes are often difficult to assess in field conditions. Here we exploited INRAE’s patrimonial ‘42-plots’ bare-fallow experiment, an unique long term experiment the world created 1928 Versailles (France), emphasize of annual inputs NPK fertilizers (ammonium, phosphate,...

Nitrogen-fixing plants, by altering the availability of soil N, potentially facilitate plant invasion. Here we describe how herbivore-driven mortality of a native Nfixing shrub, bush lupine (Lupinus arboreus), increases soil N and light availability, which promotes invasion by introduced grasses to the detriment of a native plant community. Soils under live and dead lupine stands contained larg...

There is a need to examine long-term changes in nitrogen leaching from arable soils. The purpose of this study was to analyse variations in specific leaching rates (kg ha−1 per year) and gross load (Mg per year) of N from arable land to watercourses in Sweden from a historical perspective. The start of the study was set to 1865 because information on crop distribution, yield and livestock has b...
