Soil physico-chemical properties 2007 [Countryside Survey]

This dataset consists of soil physico-chemical properties (pH, loss on ignition, bulk density, moisture content, carbon stock and concentration, total nitrogen, Olsen phosphorus) from soils sampled from up to 591 1km squares across Great Britain in 2007. The 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 Centre for Ecology & Hydrology, with repeated visits to the majority of 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, habitat areas, vegetation species data, linear habitat data, and freshwater habitat data are also gathered by Countryside Survey. Please note: the use of Olsen P data, particularly in relation to acidic soils, is controversial. Please ensure these data are suitable for your requirements and exercise caution in their use.

本数据集收录了2007年自大不列颠境内591个1平方公里方块内采集的土壤物理化学特性数据（包括pH值、灼烧失重、体积密度、含水量、碳储存和浓度、总氮、Olsen磷含量等）。乡村调查是一项对英国乡村自然资源进行独特研究或审计的科研项目。采样点基于大不列颠15公里×15公里的网格进行分层随机选取。该调查自1978年、1984年、1990年、1998年和2007年由生态与水文中心实施，并对多数方块进行了重复访问。乡村的调查采样采用严谨的科学研究方法，使我们能够将新结果与先前调查的数据进行对比。通过这种方式，我们能够探测到英国乡村随时间推移所发生的渐进性和微妙的变化。此外，乡村调查还收集了生境区域、植被物种数据、线性生境数据和淡水生境数据。请注意：Olsen P数据的运用，尤其是在酸性土壤的相关研究中，存在争议。请确保这些数据符合您的需求，并在使用时保持谨慎。
