1. 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.

2. From minerals to trees: Reducing uncertainty in estimating weathering rates for sustainable forest growth
Sammanfattning : Sustainable forest growth is fundamentally dependent on long-term supply of nutrients from mineral dissolution. Over the past century, losses of base cations (Ca, K, Mg, Na) from forest soils have been accelerated through increased forest production and anthropogenic acidification. LÄS MER
3. Organic acids and siderophores in forest soil solution

4. Acidification of Swedish forest soils : evaluation of data from the Swedish forest soil inventory
Sammanfattning : Acidification of forest soils in Sweden has negatively affected nutrient status and caused toxic effects on biota. The aim of this thesis was to investigate potential impacts of two drivers of acidification of forest soils in Sweden: (1) tree growth with subsequent harvest and (2) deposition of sulphur and nitrogen compounds.

5. DYNAMIC MODELLING OF BIOGEOCHEMICAL PROCESSES IN FOREST ECOSYSTEMS
Sammanfattning : Forests in Sweden are undergoing rapid and considerable changes regarding both management methods and environmental conditions. To understand the effects of these changes and to be able to predict impending changes in forest ecosystems, a holistic understanding of the processes governing the ecosystem is needed. LÄS MER
