1. Nitrogen Losses from a Clay-rich Soil used for Cereal Production in south-western Sweden
Sammanfattning : Addition of fertiliser nitrogen (N) in crop production increases yields and protein contents, but all is not taken up by the crop. Instead, some of the N is lost to air and waters, contributing e.g. to climate change, stratospheric ozone depletion, eutrophication and acidification. LÄS MER
2. Effects on soil solution chemistry caused by sampling method, soil treatment and vegetation
Sammanfattning : .... LÄS MER
3. Genetic adaptation to soil acidification in four grasses
Sammanfattning : Soil acidification has become a source of serious concern in many parts of the world. In southern Sweden, the deposition of acidifying substances, such as nitrogen and sulphur compounds, has decreased the mean pH of forest soils by almost one unit since the 1950s. LÄS MER
4. Organic acids and siderophores in forest soil solution
Sammanfattning : .... LÄS MER
5. Dynamics of forest soil chemistry
Sammanfattning : Acidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.
