  1. 1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Linnéa Eriksson; [2023-04-20]
    Nyckelord :soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Sammanfattning : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. LÄS MER

  3. 2. Soil health on organic farms : linking organic farmer practices to soil health and yield

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Lina Johansson; [2023]
    Nyckelord :organic farming; bulk density; management;

    Sammanfattning : Soil health is a part of the sustainable agriculture which the EU is trying to develop. Organic farming can be one way of working towards more healthy soils. The term soil health can be divided into biological, chemical, and physical aspects of the soil that are necessary to sustain the plants grown. LÄS MER

  4. 3. Future Imaginaries of Negative Emission Technologies and Folklore Myths in Icelandic Basalt: Provisional Order Emerges from the Possible Magma in the Age of ‘Hauntology’ and Broken Time

    Master-uppsats, Lunds universitet/Kulturgeografi och ekonomisk geografi; Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

    Författare :Rikke Jespersen; [2023]
    Nyckelord :NETs; Desire; Green Capitalism; Imaginaries; Storytelling; Pluriverse; Social Sciences;

    Sammanfattning : Why do we in the Western part of world today tend to believe in technology’s mythical promises rather than in folklore myths? Imaginaries of the future influence political subjects’ actions in the present and play a key role in composing the trajectory towards the future. I have critically applied this notion to the implementation of negative emission technologies in the climate-neutrality strategy. LÄS MER

  5. 4. Character and Evolution of Ore Mineralisation in the Te-Rich Enåsen Au-Cu Deposit, Central Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Pieslinger; [2023]
    Nyckelord :ore geology; partial melting; quenching textures; symplectite; tellurides; critical metals;

    Sammanfattning : The Enåsen gold deposit is located in Gävleborg county in central Sweden. Mining operations at Enåsen took place from 1984 to 1991 with Au as the main target for exploitation. The deposit has been interpreted as a metamorphosed Palaeoproterozoic analogue to near-recent epithermal Au mineralisations of a high sulphidation type. LÄS MER

  7. 5. Investigating organic fertilisers’ ability to mineralize during the first month of plant propagation

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Sebastan Farkas; [2023]
    Nyckelord :organic fertilizers; sustainability; mineralisation; nitrification;

    Sammanfattning : There are many forms of organc fertilizers produced and sold in the EU, and it can be difficult to assess which ones are the best in regards of nutrient content and the rate of mineraliztion. Two separate trials were conducted to assess the mineralization rates of three different organic fertilizers, available for private customers, on the Swedish market. LÄS MER
