11. Mitigation of phosphorus leaching from agricultural soils : improved fertilization and soil structure
Abstract : Phosphorus (P) is an essential element in crop production, but P losses from agricultural soils are a major contributor to surface water eutrophication. This thesis examined the effects of chemical soil properties and soil structure, as governed by agricultural management practices, on P leaching from agricultural soils and how this leaching can be reduced.

12. 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

13. Impact of horse-keeping on phosphorus (P) concentrations in soil and water
Abstract : Agricultural sources contribute significantly to the high phosphorus (P) loads in water, causing eutrophication in many of Europe’s water bodies. Consequently, priority has been given to reducing P leakage from sources, including soils used for animal farming. READ MORE

14. Who comes first? Implications of the plant-microbiome-soil continuum feedback on plant performance
Abstract : Plants are sessile organisms that rely on their ability to explore the soil to access the nutrients and water they need to survive. Plants have co-evolved with certain groups of bacteria and fungi that provide nutrients and water and enhance tolerance to abiotic and biotic stressors in exchange for Carbon (C). READ MORE

15. Soil moisture conditions control nutrient accumulation, carbon storage and tree growth in boreal forest landscapes
Abstract : Forest and soil properties change across landscapes due to the complex interactions between various environmental factors. In many landscapes, topography exerts a major influence on the variation in soil moisture conditions, which in turn largely affects soil properties and processes. READ MORE
