Acquisition of soil scientific measurement data as a basis for a later comparison between organic and conventional land management.

The data set contains general characteristic soil features and data on organic matter contents as well as P, K, Mg, Ca, Mg, Na, Nt, NO3,Fe, Al, Mn . They were measured at six different sites with alluvial loam sediments in Germany (four cropland and two grassland sites) belonging to one organic farm and one conventional farm at that time. Soil samples were taken for a parallel investigation at each of two comparable sites. Research domain: Soil Sciences Research question: The initial characteristics of these soils are to serve as a basis for a later study on the question of how organic farming, which has also been practiced on the conventional farm since 1988, has affected the studied characteristics over a period of now 39 and 34 years, respectively.
