Plant biomass, soil conditions and stable isotope concentrations in soil, roots and shoots from a microcosm experiment [NERC Soil Biodiversity Programme]

Data collected include: plant (shoot and root) biomass, a range of soil conditions including mycorrhizal abundance, microbial biomass carbon & nitrogen, soil extractable ammonia, soil extractable nitrate, soil extractable phosphate, total nitrogen content of soil and the presence of selected mite and collembolan species, and measurements associated with stable isotopes (ratio of isotopes of nitrogen in soil, roots and shoots, total carbon content of roots and shoots, ratio of isotopes of carbon in roots, total nitrogen content of fumigated and non-fumigated acid traps, ratio of isotopes of nitrogen in fumigated and non-fumigated acid traps). These data were collected from a laboratory-based study that examined a range of soil properties to investigate the relationship between microarthropods and soil microbial properties and the short-term partitioning of a dual-labelled organic nitrogen source (glycine-2-13C-15N) between a grassland plant, Agrostis capillaris, and the soil microbial biomass, to determine how soil fauna and their diversity influence plant-microbial competition for organic N. The experiment was carried out at Lancaster University using soil from the NERC Soil Biodiversity site in Scotland. The work was part of the NERC Soil Biodiversity Thematic Programme, which was established in 1999 and was centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute) farm at Sourhope in the Scottish Borders. During the programme, the site was monitored to assess changes in above-ground biomass production (productivity), species composition and relative abundance (diversity).

所收集的数据包括：植物（茎和根）的生物量、一系列土壤条件（包括菌根丰度）、微生物生物量碳和氮、土壤可提取氨、土壤可提取硝酸盐、土壤可提取磷酸盐、土壤总氮含量，以及选定的螨和线蚯蚓物种的存在，以及与稳定同位素相关的测量（土壤、根和茎中氮同位素的比例、根和茎的总碳含量、根中碳同位素的比例、熏蒸和非熏蒸酸捕集器中总氮含量、熏蒸和非熏蒸酸捕集器中氮同位素的比例）。这些数据来自一项基于实验室的研究，该研究旨在调查微节肢动物与土壤微生物特性之间的关系，以及双标记有机氮源（甘氨酸-2-13C-15N）在草地植物（细羊茅，Agrostis capillaris）和土壤微生物生物量之间的短期分配，以确定土壤动物及其多样性如何影响植物与微生物对有机氮的竞争。实验在兰卡斯特大学进行，使用苏格兰NERC土壤生物多样性站点的土壤。该研究是NERC土壤生物多样性主题计划的一部分，该计划于1999年设立，其核心是对位于苏格兰边境Sourhope的Macaulay土地利用研究所（现更名为詹姆斯·哈顿研究所）农场的大型田间实验进行深入研究。在该计划期间，对该地点进行了监测，以评估地上生物量生产（生产力）、物种组成和相对丰度（多样性）的变化。有关该数据集的详细信息，请参阅https://doi.org/10.5285/e3c79781-09af-4c4f-b6ad-b0bc323e203f
