Cluster Marchfeld - Database on soil parameters and yields of diverse tillage systems from three 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 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 database compromise of 1153 records and was built with Microsoft Access 2019. The provided files (Marchfeld Cluster) contains data on a) agricultural management, b) primary production (crop yield), c) soil parameters (organic carbon and nitrogen concentration) collected at three LTER experimental sites, and d) socio-ecological parameters gathered for the 23 municipalities encompassing and surrounding the three LTER sites. These socio-economic data have a longer focus period (1970-2023) in order to capture and present the influences of gradual changes in the region's socio-economic and biophysical framework. As the socio-ecological parameters are third-party data, reference is made to their source (see: file "ClusterMarchfeld_Socioecological.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").农业生态“马尔希费尔德（Marchfeld）”集群针对奥地利3个长期生态研究（Long-Term Ecological Research, LTER）站点，于2018-2022年评估了耕作方式对作物产量及选定土壤参数的影响。所有站点的耕作模式分为两类：浅耕减耕（耕作深度10~15 cm）与铧式犁深耕（耕作深度25~30 cm）。在常规耕作的研究站点中，还增设了更多耕作梯度，主要包括免耕与浅少耕（耕作深度5~8 cm）。由于各LTER站点的运营周期长达6至34年，本次研究的参数可反映影响当前状态的累积性历史演化过程。该集群的3个LTER站点组成统一研究组，即奥地利潘诺尼亚地区的马尔希费尔德LTER集群，其涵盖多样化的作物轮作体系、差异化的农业管理模式（2个常规管理站点与1个有机管理站点）以及多种耕作制度。 马尔希费尔德集群数据库包含1153条记录，基于Microsoft Access 2019构建。本次提供的《马尔希费尔德集群》数据集文件包含四类数据：a）农业管理数据；b）初级生产（作物产量）数据；c）在3个LTER实验站点采集的土壤参数（有机碳与氮浓度）数据；d）覆盖并环绕这3个站点的23个行政区的社会生态参数数据。这类社会经济数据的观测周期更长（1970-2023年），旨在完整呈现区域社会经济与生物物理框架的渐进变化所带来的影响。由于社会生态参数为第三方数据，其来源详见配套文件"ClusterMarchfeld_Socioecological.csv"。 土壤参数涵盖不同土层深度，通常以10 cm为间隔（MUBIL站点为15 cm），其中MUBIL、GE、FB三个站点的最大采样深度分别可达30 cm、50 cm和100 cm。此外，关于野外研究站点、实验设计、分析方法、采样方案以及数据库结构的详细信息，已发表于待评审的数据集相关论文中。
