  1. 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 Environment

    Author : Fanny Otterlin Karlsson; [2024]
    Keywords : agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Abstract : 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

  3. 2. The potential nitrous oxide emissions in a permanent grassland chronosequence

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Sandra Lillsjö Kronblad; [2023]
    Keywords : nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

    Abstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

  4. 3. Underlying mechanisms behind nitrous oxide emissions in oilseed radish, Raphanus sativus var. oleiformis, and Phacelia tanacetifolia

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Annika Swensson Källén; [2023]
    Keywords : nitrous oxide; glucosinolates; greenhouse gases; oilseed radish; Phacelia tanacetifolia; cover crops; labile C;

    Abstract : Greenhouse gases are a driving force of climate change and the annual greenhouse gas emissions were higher between 2010-2019 than any other time in human history (Skea et. al. 2022). READ MORE

  5. 4. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Naga Deepika Peddamudium; [2023]
    Keywords : Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Abstract : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. READ MORE

  6. 5. Emission of greenhouse gases from constructed wetlands : Nutrient status in relation to methane and nitrous oxide emission

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Christian Lundström; [2022]
    Keywords : Constructed wetland; greenhouse gas emission; nutrient status; ebullition; Anlagd våtmark; växthusgasutsläpp; näringsstatus; ebullition;

    Abstract : Agricultural land releases large amounts of nitrogen and phosphorus to water bodies which causes eutrophication. Creating wetlands on agricultural land is one way to prevent this major issue. However, constructed wetlands are a large emission source of greenhouse gases. READ MORE
