摘要: Analysis of data from the National Soil Inventory England and Wales obtained between 1978 2003 shows widespread increases in soil pH - i.e., soils became less acid across both countries during survey period. In general, increased under all land uses. At least part increase its regional variation could be explained by decreased sulphur deposition atmosphere. Changes liming practices on arable probably also contributed. The effect was moderated use, properties particularly organic carbon content level past deposition.
