1. 1. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

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

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

   Sammanfattning : 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. LÄS MER

3. 2. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

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

   Författare :Liliana Marcela Daza Gomez; [2023]
   Nyckelord :nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

   Sammanfattning : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. LÄS MER

4. 3. Långsiktig torvnedbrytning för olika vegetationstyper på dikad skogsmark

   Kandidat-uppsats, SLU/School for Forest Management

   Författare :Carl Carlsson; Sofie Jönsson; [2023]
   Nyckelord :växthusgaser; torvmark; dikning;

   Sammanfattning : Skogsklädda torvmarker i Sverige dikades i stor utsträckning mellan 1930- och 1980-talen i syfte att höja virkesproduktionen. Till följd av klimatproblemet har intresset för dikade torvmarkers bidrag till växthusgasutsläppen ökat under de senaste decennierna. LÄS MER

5. 4. Greenhouse gas emissions and carbon burial in a small pond

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

   Författare :Maria Carlson; [2023]
   Nyckelord :Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

   Sammanfattning : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. LÄS MER

7. 5. IMPLEMENTATION OF NITROGEN RECOVERY AT WASTEWATER TREATMENT PLANTS TO COMPLEMENT ARTIFICIAL FERTILISER PRODUCTION : An investigation of the nitrogen recovery potential, energy consumption and environmental impacts at Kungsängens wastewater treatment plant in Västerås, Sweden

   Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Cassandra Kestran; Olivia Larsson; [2023]
   Nyckelord :Ammonia stripping; Eutrophication; Fertiliser production; Gas permeable membrane; Haber-Bosch; Nitrogen management; Nitrogen recovery technologies; Nitrogen removal; Reject water;

   Sammanfattning : As Kungsängens wastewater treatment plant is considering a move, it opens up a possibility to implement nitrogen recovery technologies that comply with current and future legislative requirements. Nitrogen recovery offers simultaneous treatment of wastewater and collection of concentrated ammonia products for fertiliser production. LÄS MER
