1. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments
Abstract : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. READ MORE

2. Digital wet areas mapping
Abstract : Wet soil in forested landscapes of the boreal zone is often associated with large open wetlands or peatlands, but it may also be hidden beneath closed forest canopies on drained wetlands or wet strips beside streams known as riparian zones. Since these wet areas are shrouded by canopy they have traditionally been difficult to map from aerial photographs. READ MORE

3. Improved farm soil mapping using near infrared reflection spectroscopy
Abstract : Information on soil texture, soil organic matter content (SOM), nutrient status and pH is fundamental for efficient crop production and for minimising negative effects on the environment. Farmers obtain this information, on which decisions on fertiliser and lime requirements are based, through farm soil mapping. READ MORE

4. Digital soil mapping and portable X-ray fluorescence prediction of cadmium, copper and zinc concentrations as decision support for crop production
Abstract : Trace element concentrations in agricultural soil are important for crop production. Certain trace elements, e.g. copper (Cu) and zinc (Zn), are essential for crops to complete their life cycle. READ MORE

5. Hydrological Modelling, Topographical Influence and Yield Mapping in Precision Agriculture
Abstract : The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. READ MORE
