1. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities
Abstract : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. READ MORE

2. Novel approaches in modeling of soil carbon : Upscaling theories and energetics
Abstract : Soils contain more carbon (C) than terrestrial (above ground) and atmospheric carbon combined. Mismanagement of soil C could lead to increased greenhouse gas emissions, whereas practices leading to increased C storage would help mitigate climate change while improving soil fertility and ecological functions.

3. Recycling Filter Substrates used for Phosphorus Removal from Wastewater as Soil Amendments
Abstract : 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

4. Phosphorus availability and microbial respiration across biomes : from plantation forest to tundra
Abstract : Phosphorus is the main limiting nutrient for plant growth in large areas of the world and the availability of phosphorus to plants and microbes can be strongly affected by soil properties. Even though the phosphorus cycle has been studied extensively, much remains unknown about the key processes governing phosphorus availability in different environments. READ MORE

5. Ectomycorrhizal Fungal Mycelial Dynamics and its Role in Forest Soil Carbon Cycling
Abstract : Most boreal tree species rely on root-associated ectomycorrhizal fungi for nutrient acquisition, in exchange the trees allocate part of their photosynthetically fixed carbon (C) to these fungi. This has a feedback on soil C dynamics as mycorrhizal fungi are important in regulating soil C cycling and storage. READ MORE
