The Ossekampen Grassland Experiment: Data underlying the publication: A matter of time: recovery of plant species diversity in wild plant communities at declining nitrogen deposition

The Ossekampen long term grassland experiment (Wageningen, The Netherlands) was started in 1958 in an extensively grazed species-rich grassland. The treatments consist of several combinations of nitrogen, phosphorus and potassium application. The measurements include above ground yields, soil quality and botanical composition.
