1. Soil nitrogen fluxes and root uptake in the boreal forest
Abstract : Nitrogen (N) is essential for growth and net primary production of plants. However, N acquisition by plants is influenced by movement of soil N compounds from bulk soil to plant roots and uptake of N by roots. This thesis is aimed at deepening our knowledge on these key processes involved in plant N acquisition in the N-limited boreal forest. READ MORE

2. Chlorine Cycling in Terrestrial Environments
University dissertation from Linköping : Linköping University Electronic PressAbstract : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. READ MORE

3. Importance of tannins for responses of aspen to anthropogenic nitrogen enrichment
University dissertation from Umeå : Umeå UniversityAbstract : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. READ MORE

4. Recycling Filter Substrates used for Phosphorus Removal from Wastewater as Soil Amendments
University dissertation from Stockholm : KTHAbstract : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. READ MORE

5. Influence of soil amendments and soil properties on macro– and micronutrient availability to microorganisms and plants
University dissertation from Stockholm : KTHAbstract : Utilising by-products from industrial and domestic activities and from bioenergy production is one of the new ways of recovering and re-using nutrient resources in agriculture. However, these by-products can potentially add toxic elements or alter soil properties in ways that harm the soil and related environments. READ MORE
