Topsoil physico-chemical properties from the UKCEH Countryside Survey, Great Britain, 2020, v2

This dataset consists of measures of topsoil (0-15 cm) physico-chemical properties from soils sampled from 48 x 1-km squares across Great Britain in 2020 as part of a rolling soil and vegetation monitoring program of 500 1-km squares repeated every 5 years. The properties included are: pH, soil organic matter (loss on ignition, LOI), derived carbon concentration and carbon stock (SOC), soil group, soil bulk density of fine earth, soil moisture of wet soil, fine earth volumetric water content (dry), nitrogen concentration and stock, and Olsen-phosphorus concentration. The UKCEH Countryside Survey is a unique study or 'audit' of the natural resources of the UK's countryside. The sample sites are chosen from a stratified random sample, based on a 15 by 15 km grid of GB. Surveys have been carried out in 1978, 1984, 1990, 1998 and 2007 by the UK Centre for Ecology & Hydrology (UKCEH) and predecessors, with repeated visits to most of the squares. The countryside is sampled and surveyed using rigorous scientific methods, allowing us to compare new results with those from previous surveys. In this way, we can detect the gradual and subtle changes that occur in the UK's countryside over time. In addition to soil data, vegetation species data are also gathered by the current phase of the UKCEH Countryside Survey. This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

本数据集汇聚了2020年自大不列颠48个1平方公里方块中采集的表层土壤（0-15厘米）的物理化学特性度量值，该采集工作作为一项每五年重复一次、覆盖500个1平方公里方块的滚动式土壤与植被监测计划的一部分。所包含的特性包括：pH值、土壤有机质（灼烧损失，LOI）、派生碳浓度及碳储量（SOC）、土壤类型、细粒土壤的土壤容重、湿润土壤的土壤水分、细粒土壤的体积含水率（干燥状态）、氮浓度及储量，以及Olsen磷浓度。英国乡村调查（UKCEH Countryside Survey）是对英国乡村自然资源进行的一次独特研究或‘审计’。采样点基于大不列颠15公里x15公里的网格进行分层随机选择。调查始于1978年，1984年，1990年，1998年和2007年，由英国生态与水文学中心（UKCEH）及其前身机构执行，并对大多数方块进行了重复访问。乡村的采样与调查采用严格的科学方法，使我们能够将新结果与前期调查结果进行比较。通过这种方式，我们能够探测到英国乡村随时间发生的渐变和微妙变化。除了土壤数据外，当前阶段的英国乡村调查还收集了植被物种数据。此研究工作得到了自然环境研究委员会（Natural Environment Research Council）提供的NE/R016429/1号奖项的支持，作为英国-SCAPE项目的一部分，旨在提供国家能力。有关本数据集的详细信息可在https://doi.org/10.5285/6a3382cc-f5f4-4d68-9517-c62fadd8af4f查阅。
