  1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  3. 2. Effective soil organic carbon monitoring in perennial agriculture systems - Sampling protocol development and evaluation

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

    Författare :Maja Holm; [2024]
    Nyckelord :Physical geography; ecosystem science; soil organic carbon; soil sampling; perennial crops; carbon sequestration; carbon farming; Kernza™; soil organic carbon stock; Earth and Environmental Sciences;

    Sammanfattning : Perennial agriculture systems are gaining ground as a more sustainable alternative to conventional annual agriculture, partly for their potential to increase the soil organic carbon (SOC) content. Carbon farming is another hot topic for SOC sequestration, as it creates economic incentives for farmers. LÄS MER

  4. 3. 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

  5. 4. Stadsträd – i nöd och lust : skillnader i reglerande och stödjande ekosystemtjänster mellan löv- och barrträd i stadsmiljö

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Jennifer Engelbrekt Tchang; Sara Karlsson; [2023]
    Nyckelord :ekosystemtjänst; lövträd; barrträd; stadsträd; luftrening; dagvattenhantering; vindskydd; temperaturreglering; kolupptagning; kolinlagring; biologisk mångfald;

    Sammanfattning : Träd har en viktig roll i att klimatanpassa städer genom att leverera ekosystemtjänster. I nordiska städer planteras mest lövträd eftersom det historiskt funnits ett kulturellt motstånd mot barrträd. LÄS MER

  7. 5. Soil Organic Carbon in Boreal Agricultural Soil : Tillage interruption and its effect on Soil Organic Carbon

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Hilda Alfredsson; [2023]
    Nyckelord :soil organic carbon; agriculture; tillage interruption; carbon sequestration;

    Sammanfattning : Farmers have been disrupting the carbon cycle ever since humans started converting forests to agricultural lands. But are there farming practices that can be applied to increase the carbon storage in the soil and subsequently counteract increasing carbon dioxide levels in the atmosphere? In this study I investigate if soil organic matter (SOM) and soil organic carbon (SOC) change with longer interruption between tillage events. LÄS MER
