Cluster Marchfeld - Database on soil parameters and yields of diverse tillage systems from three long-term experimental (LTER) sites in Austria (2018-2022)

The agroecological “Marchfeld” cluster assess the impacts of tillage on crop yield and selected soil parameters, at three Austrian long-term experimental (LTER) sites in the years 2018 to 2022. Tillage at all sites consists of a reduced (soil depth 10-15 cm) and a mouldboard ploughing (25-30 cm) system. On the conventionally farmed study sites, further gradations of tillage were introduced, mainly no-till and minimum tillage (5-8 cm). Since the LTER sites are operated over a long period of time (between 34 and 6 years), our parameters show cumulative historical developments that influence the present. All three LTER sites are combined in a coherent group, the LTER Cluster “Marchfeld” of the Pannonian region in Austria with diverse crop rotations, varying agricultural management systems (two conventionally and one organically managed) and different tillage systems. The Marchfeld cluster data set compromise of 1153 records and was built with Microsoft Access 2019. The provided files (Marchfeld Cluster) contains data on a) agricultural management (own csv), b) primary production (crop yield), c) soil parameters (organic carbon and nitrogen concentration) collected at three LTER experimental sites. The structure of the two csv files is provided through ClusterMarchfeld_DataDescription.csv. The soil parameters are available for various soil depths, usually in 10 cm (MUBIL: 15 cm) increments up to 30, 50 or 100 cm for MUBIL, GE and FB, respectively. Further, detailed information about the field study sites, experimental design, analytical methods, sampling design and detailed information about the structure of the database, are offered in the data publication ("under review"). All agricultural management practices are listed in Agricultural_Management.csv with date and detailed description. Furthermore, a distinction is made between general management (whole plot) and specific management (specific plot = tillage). Tillage is further subdivided to their specific factor..
