Core Project 9 - Soil - will continue to organize the coordinated soil sampling and compile important baseline soil properties. It will also support the large multi-site experiments in forest and grassland. To this end, we will organize the fifth coordinated soil sampling on the experimental plots as well as on the multi-site experiments at the beginning of the new project phase. The coordinated soil sampling will allow all soil-related projects in the Biodiversity Exploratories to work on the same samples. To provide comprehensive carbon and nutrient balances of the Biodiversity Exploratories, subsoils will be sampled for the first time at all Experimental Plots (EPs). In addition, and to complement carbon release data, we are investigating microbial carbon-dioxide fixation at all EPs. We will also continue to determine important soil properties such as pH, carbon, and nutrient contents, root contents, clay contents, stone contents that have been monitored since 2011. At the forest plots, we additionally investigate enzyme activities and microbial biomass. In the forest, we have also been recording litter input since 2015. This allows us to capture important ecosystem functions and services related to carbon and nutrient cycling. In addition, we use land use and climate data to analyze their impact on important soil functions, such as soil carbon storage. Our soil data also allow us to analyze important long-term effects of land use and biodiversity change, and climate extremes on soil properties. Overall, this project will provide soil data and information at all study sites that are highly relevant to all other projects, especially to all synthesis projects.

核心项目9-土壤 - 将继续组织协调的土壤采样并编译重要的基线土壤特性。它还将支持森林和草原的大型多站点实验。为此，我们将在新项目阶段开始时在实验图以及多站点实验上组织第五次协调的土壤采样。协调的土壤采样将允许生物多样性探索者中的所有与土壤相关的项目在相同的样品上工作。为了提供生物多样性探索者的综合碳和营养平衡，将首次在所有实验图（EPS）上首次采样底土。此外，为了补充碳释放数据，我们正在研究所有EPS的微生物二氧化碳固定。我们还将继续确定重要的土壤特性，例如pH，碳和养分含量，根内容物，粘土含量，自2011年以来一直受过监测的石材含量。在森林地块上，我们还研究了酶活性和微生物生物量。在森林中，我们还一直在录制自2015年以来的垃圾输入。这使我们能够捕获与碳和营养循环有关的重要生态系统功能和服务。此外，我们使用土地利用和气候数据来分析其对重要土壤功能（例如土壤碳储存）的影响。我们的土壤数据还使我们能够分析土地使用和生物多样性变化的重要长期影响，以及对土壤特性的极端气候。总体而言，该项目将在与所有其他项目相关的所有研究网站上提供土壤数据和信息，尤其是与所有合成项目。
