Topsoil pH estimates from the Countryside Survey of Great Britain, 2007 using a generalized additive model

This dataset presents modelled estimates of soil pH at 1km2 resolution across Great Britain. A Generalized Additive Model approach was used with Countryside Survey soil pH data from 2007 and including climate, atmospheric deposition, habitat, soil and spatial predictors. The model is based on soil pH data from 2446 locations across Great Britain and is representative of 0-15 cm soil depth. Soil pH was measured using 10g of field moist soil with 25ml de-ionised water giving a ratio of soil to water of 1:2.5 by weight. The Countryside Survey looks at a range of physical, chemical and biological properties of the topsoil from a representative sample of habitats across the UK. 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.

本数据集展示了基于1平方公里分辨率的英国土壤pH值的模拟估计。该模型采用广义加性模型方法，结合了2007年乡村调查的土壤pH值数据，并纳入了气候、大气沉降、栖息地、土壤和空间预测因子。模型基于英国2446个地点的土壤pH值数据，并代表了0-15厘米的土壤深度。土壤pH值是通过使用10克田间湿润土壤与25毫升去离子水进行测量，以1:2.5的土壤与水重量比获得。乡村调查旨在对英国代表性栖息地表层土壤的多种物理、化学和生物特性进行考察。该研究得到自然环境研究委员会（Natural Environment Research Council）资助，项目编号NE/R016429/1，作为英国-SCAPE项目的一部分，旨在提升国家能力。关于本数据集的详细信息可在以下链接找到：https://doi.org/10.5285/4b0e364d-61e6-48fb-8973-5eb18fb454cd
