Abstract

Atmospheric deposition and its impact on soil and soil processes is a major agricultural and environmental problem. Acid rain has been the chief concern for many years, with sulphur from power stations and industry causing the acidification of soil and waters, reducing crop yields in the most severe cases, and always impacting on biodiversity. Now nitrogen is the main atmospheric pollutant, eutrophying as well as acidifying soils and waters. It has been calculated that more than twice as much reactive nitrogen is emitted as in pre-industrial times. Whilst some forms have only localised effects, other forms, especially oxidised species are transported around the globe, disturbing ecosystems. This project measures atmospheric nitrogen deposition and the impacts of deposited nitrogen, especially on nitrogen cycling processes in soil. Its objectives are: 1. To continue to measure all forms of nitrogen deposited to land and the variations with time and space. 2. To use stable isotope techniques with 15N to measure the impacts of atmospheric N on soil processes specifically and ecosystems generally.
