  1. 1. 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

  3. 2. Enhancing Mineral Carbonation of Olivine with CO2

    Master-uppsats, KTH/Kemiteknik

    Författare :Ikaros Altantzis; [2023]
    Nyckelord :CO2 sequestration; Dissolution rate; Mineral carbonation; Olivine; Particle size; CO2-inlagring; Upplösningshastighet; Mineral kolsyrning; Olivin; Partikelstorlek;

    Sammanfattning : Koldioxidutsläpp (CO2) från energiproduktionsindustrin och transportsektorn globalt påverkar miljön negativt. Länder har enats om att minska utsläppen för att nå målet om en genomsnittlig temperaturökning på 1,5 °C till 2030. LÄS MER

  4. 3. Separation and acidification of digested animal manure : properties of the future organic fertilizers

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

    Författare :Marie Björs; [2023]
    Nyckelord :Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Sammanfattning : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. LÄS MER

  5. 4. ARCTIC MYCORRHIZAL INTERACTIONS UNDER CLIMATE CHANGE

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

    Författare :Otto Minas; [2022-07-06]
    Nyckelord :Climate change; Arctic ecology; arbuscular mycorrhiza; graminoids; plant ecology; soil ecology; carbon cycle.;

    Sammanfattning : The Arctic is experiencing climate change at an extreme rate, affecting both the rates of plant growth and nutrient cycling. Due to the changes in temperature, but also in nutrient cycling, with increased nutrient mineralization and decreasing P:N ratio (phosphorus, P and nitrogen, N), the arbuscular mycorrhizal fungi (AM) that are prevalent in warmer soils have shown the potential to increase in the otherwise unfavorable Arctic environment.

  7. 5. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Tsai-wei Tang; [2022-01-26]
    Nyckelord :N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

    Sammanfattning : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. LÄS MER
