Soil physico-chemical properties 1998 [Countryside Survey]

This dataset consists of soil physico-chemical properties (pH, loss on ignition, carbon stock and concentration, total nitrogen, Olsen phosphorus) from soils sampled across Great Britain in 1998. 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.

本数据集囊括了1998年采集于大不列颠各地土壤的物理化学性质（包括pH值、灼失量、碳储量及浓度、全氮含量、Olsen磷含量）等信息。乡村调查是一项独特的英国乡村自然资源评估研究或审计。样本点基于GB地区的15×15公里网格进行分层随机抽样选取。该调查自1978年起，每隔六年（1984年、1990年、1998年、2007年）由生态与水文学研究中心实施，并对大多数样本点进行了重复考察。乡村调查采用严谨的科学研究方法，使得我们能够将新数据与先前调查结果进行对比分析，从而探测出英国乡村随时间推移所发生的渐进且微妙的变迁。此外，乡村调查还收集了生境面积、植被物种数据、线性生境数据和淡水生境数据。请注意：Olsen磷数据，尤其是在酸性土壤中的应用，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。关于本数据集的详细信息，请参阅https://doi.org/10.5285/9d1eada2-3f8b-4a7b-a9b0-a7a04d05ff72。
