1. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. READ MORE

2. Soil compaction and the effect on infiltration in urban green environments : A study based on field measurements and HYDRUS 1D modelling
University essay fromAbstract : The consequences of recent flooding and extreme rain events have highlighted the importance of proper urban planning and preventative measures for storm water management. As cities become more urbanized the significance of permeable surfaces such as parks and other urban green spaces increases which infiltrate the water into the ground. READ MORE

3. Multifunctional ice and snow repellent coatings for photovoltaic modules
University essay from Uppsala universitet/SolcellsteknikAbstract : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. READ MORE

4. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping
University essay from SLU/Dept. of EcologyAbstract : More than 60% of anthropogenic nitrous oxide (N2O) emissions are attributed to agricultural activities. N2O production in soils highly depends on the N availability along with other factors such as soil moisture content, which provide suitable conditions for nitrification and denitrification. READ MORE

5. Emissions of nitrous oxide associated with frost killed cover crops
University essay from SLU/Dept. of Biosystems and Technology (from 130101)Abstract : Agriculture is responsible for approximately 80% of anthropogenic emissions of the potent and long-lived greenhouse gas nitrous oxide (N2O). N2O emissions from agricultural soils are characterized by high temporal and spatial variability and often peak in short bursts related to events such as precipitation, fertilization and soil thawing.
