  1. 1. Effekten av olika brukningsmetoder på kolinlagring i åkermark

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Sanna Magnusson; [2022]
    Nyckelord :Soil organic carbon; SOC; carbon sequestration; soil health; agriculture; arable land; crop production; Sweden; cover crops; no-till; reduced tilling; organic amendments; harvest residues; crop rotation; legumes; perennial crops; agroforestry; combined management practices.; Earth and Environmental Sciences;

    Sammanfattning : Increased carbon sequestration in agricultural land is an important measure to reduce global warming. Since the soil is a large carbon sink, a small change in the soil organic carbon (SOC) stocks can make a substantial difference to the carbon dioxide content in the atmosphere. LÄS MER

  3. 2. Hur påverkas markorganismerna av jordbruksmetoden strukturkalkning?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Maria Gustavsson; [2021]
    Nyckelord :structural liming; agriculture; microorganisms; clay soil; respiration; earthworm population; Earth and Environmental Sciences;

    Sammanfattning : This field study was done to get an understanding of how the agricultural method called “structural liming” might affect soil organisms in a negative way. Soil organisms are crucial as they perform biological processes that improve good soil structure. This is important as it enables sustainable food production, today, and in the future. LÄS MER

  4. 3. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Aida Esmailzadeh Davani; [2021]
    Nyckelord :Physical Geography; Ecosystem Analysis; Permafrost; CH4 flux; CO2 flux; Abisko; Wetlands; Earth and Environmental Sciences;

    Sammanfattning : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. LÄS MER

  5. 4. Torrsubstansförluster vid lagring och hantering av träspån vid Härjeåns Energi AB

    Master-uppsats, Karlstads universitet/Science, Mathematics and Engineering Education Research (SMEER)

    Författare :Johanna Arnberg; [2018]
    Nyckelord :torrsubstansförlust; lagring; träspån; nedbrytning;

    Sammanfattning : Härjeåns Energi AB är ett företag beläget i Sveg, som består av ett helt nytt kraftvärmeverk samt en biobränslefabrik där företaget producerar bland annat pellets av träspån. Innan pelletering lagras spånet i en stor stack. LÄS MER

  7. 5. Multiple Substrate-Induced Respiration and Isothermal Calorimetry : Applicability in Risk Assessment of Contaminated Soil

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Caroline Wright; [2017]
    Nyckelord :Risk assessment; biological indicators; multiple substrate-induced respiration; MSIR; MicroRespTM; isothermal calorimetry; calorespirometric ratio; contamination; Cu; PAH; Riskbedömning; biologiska indikatorer; multipla substrat-inducerad respiration; MSIR; MicroRespTM; isotermisk kalorimetri; calorespirometric ratio; förorening; Cu; PAH;

    Sammanfattning : At present, soils face great threats. Consequences of human activities, such as climate change, acidification and contamination result in decreased soil health. This is a threat to human health and well-being, since our society is dependent on soil ecosystem services. LÄS MER
