Long-term Field Experiments in Germany

This dataset provides detailed information about 205 Long-term Field Experiments (LTFE) in Germany. The research was done in the context of the funding initiative of the German Federal Ministry for Education and Research (BMBF) 'BonaRes' (www.bonares.de). LTFE here are defined as agricultural field experiments with the minimum duration of 20 years, a static design and research in the context of bioeconomy. Experiments with a duration of less than 20 years but reaching this age during the BonaRes funding period (2015-2024) are considered as LTFE as well.
Information about duration, research theme, holding institution, research parameters, location, landuse category, membership in networks, size and experimental setup are provided.
In addition BonaRes performed a classification of the experiments and assigned them to five soil functions. The classification was done according to our knowledge about the data which was collected in the respective LTFE up to now. The following five soil functions were chosen as most relevant for BonaRes: biomass production, storage and filtering of water, storage and recycling of nutrients, carbon storage, habitat for biological activity.

本数据集收录了德国境内205项长期田间试验（Long-term Field Experiments, LTFE）的详细信息。本研究依托德国联邦教育与研究部（BMBF）资助的BonaRes计划（www.bonares.de）开展。此处所指的长期田间试验，定义为最短持续时长20年、采用固定试验设计且围绕生物经济开展的农业田间试验；若试验时长不足20年，但在BonaRes资助周期（2015-2024）内达到20年时长，同样纳入本数据集的LTFE范畴。
数据集涵盖试验时长、研究主题、依托机构、研究参数、试验地点、土地利用类别、所属网络、试验规模及试验设计方案等信息。
此外，BonaRes团队针对所有收录试验完成了分类，将其划归为5类土壤功能。本次分类依据截至目前各相关LTFE的已采集观测数据开展。本次遴选的5项与BonaRes关联最为紧密的土壤功能分别为：生物质生产、水体储存与过滤、养分储存与循环、碳储存、生物活动栖息地。
