对1978年至2003年期间获得的英格兰和威尔士国家土壤调查数据的分析表明，在调查期间，两国的土壤pH值普遍上升--即土壤变得不那么酸了。总体而言，在所有土地利用方式下，土壤pH值都有所增加。至少部分增加及其区域差异可以用大气中硫沉积的减少来解释。在耕地上施石灰的做法的改变可能也起到了作用。硫沉积减少的影响受到土地利用、土壤性质--特别是土壤pH值和有机碳含量--以及过去硫沉积水平的影响。
Analysis of data from the National Soil Inventory of England and Wales obtained between 1978 and 2003 shows widespread increases in soil pH - i.e., soils became less acid - across both countries during the survey period. In general, soil pH increased under all land uses. At least part of the increase and its regional variation could be explained by decreased sulphur deposition from the atmosphere. Changes in liming practices on arable land probably also contributed. The effect of decreased sulphur deposition was moderated by land use, soil properties - particularly soil pH and organic carbon content - and the level of past sulphur deposition.
