Long-term data set for soil characteristics on a set aside area in North-East Germany

On set-aside areas, which there agricultural used for a long, the soil parameters have a special dynamic. After a long period of anthropogenic use they are moving back to a level typically for the site without any use. For an area on a sandy site (sandy loam-soil, German soil quality index for arable land: 25...35, mean(1988-2017) annual precipitation: 544 mm, mean (1988-2017) annual temperature: 9.3°C) in the Müncheberg area (Federal State of Brandenburg, Germany) for the period 1992-2017 measured values for the most important soil parameters with fast dynamics (NO3, NH4, Nan, soil water) and slow dynamics (pH, Nt, P, K, Mg, Ct) are available for three soil layers (0-30 cm, 30-60 cm and 60-90 cm). Generally these measured values are available annually in spring time. For the years 1992-1996, however, several measurements per year are available also until the end of the vegetation. The area, which has been set-aside since 1992, was used for agriculture until 1991 (recurrent winter rye cultivation). Since 1992 the set-aside area was mulched annually to prevent succession.
