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 (direct seeding) 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 (subplot = tillage). Tillage is further subdivided to their specific treatment.农业生态"马尔希费尔德（Marchfeld）"数据集集群于2018至2022年间，针对奥地利3个长期生态研究（Long-Term Ecological Research，LTER）试验站点，评估耕作方式对作物产量及选定土壤参数的影响。所有站点的耕作方式均包含减耕（耕作深度10~15 cm）与铧式犁耕（耕作深度25~30 cm）两种体系。在常规耕作的试验站点中，还增设了更多梯度的耕作处理，主要为免耕（直接播种）与少耕（耕作深度5~8 cm）。由于这些LTER站点已长期运行（时长介于34年至6年之间），本数据集的参数能够反映影响当前状态的累积历史演变过程。3个LTER站点共同组成一个统一集群——奥地利潘诺尼亚地区的LTER"马尔希费尔德"集群，该集群涵盖多样化的作物轮作模式、差异化的农业管理体系（2个常规管理站点与1个有机管理站点）以及多种耕作方式体系。 马尔希费尔德数据集集群共包含1153条记录，基于微软Access 2019构建而成。本次提供的"马尔希费尔德集群"文件包含三类数据：a）农业管理数据（独立csv文件）、b）初级生产数据（作物产量）、c）从3个LTER试验站点采集的土壤参数数据（有机碳与氮浓度）。两个csv文件的结构说明可通过ClusterMarchfeld_DataDescription.csv文件获取。 土壤参数涵盖不同土层深度，通常以10 cm为间隔采集（MUBIL站点为15 cm）；其中MUBIL、GE、FB三个站点的采样深度分别可达30 cm、50 cm与100 cm。此外，关于田间试验站点、试验设计、分析方法、采样方案以及数据库结构的详细说明，已收录于正在审稿的数据发表论文中。所有农业管理措施均已在Agricultural_Management.csv文件中按日期列出，并附带详细说明。此外，数据集还区分了通用管理（全地块）与特定管理（亚地块=耕作处理）两类管理模式，耕作处理还可进一步细分为具体的试验处理。
