  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. Odlade torvjordar och växthusavgång : effekter av pH, temperatur och vattenhalt

    University essay from SLU/Dept. of Soil and Environment

    Author : Lisette Nordgren; [2021]
    Keywords : odlad torvjord; pH; kalk; växthusgaser;

    Abstract : Torvmarker utgör potentiella sänkor av växthusgaser (VHG) och täcker en betydande andel av Sveriges yta. Förra seklet dikades en stor del av markerna för odling m.m. vilket i nutid har lett till en ökande problematik med mikrobiell nedbrytning och torvförlust. READ MORE

  4. 3. Kalkningens påverkan på växthusgasemissioner från odlad torvjord

    University essay from SLU/Dept. of Soil and Environment

    Author : Lisa Jörblad; [2018]
    Keywords : CO2; N2O; dränering; skrymdensitet; nedbrytning; vattenhalt;

    Abstract : Peat soils are used for agriculture and to improve the conditions they are drained and limed. These actions lead to improved living conditions for the microorganisms that live in the soil which increases the decomposition of the organic matter. READ MORE

  5. 4. Växthusgasutsläpp vid sandinblandning i torvjordar

    University essay from SLU/Dept. of Soil and Environment

    Author : Andreas Mattsson; [2018]
    Keywords : torv; sand; gjuterisand; koldioxid; växthusgasutsläpp;

    Abstract : Peat soils are organic soils which make up significant parts of Sweden land area. Peat soils are commonly used in agriculture. Growing crops in these soils require drainage which speeds up the degradation of the organic matter and increases the greenhouse gas emissions. READ MORE

  6. 5. Liming and deep cultivation as long term mitigation actions to lower the rate of peat decomposition and CO2 emissions from peat soils

    University essay from SLU/Dept. of Soil and Environment

    Author : Joakim Hermansson; [2017]
    Keywords : peat soil; organic soil; decomposition; CO2 emission; water retention;

    Abstract : Cultivated drained peat soils have a complex relationship towards CO2 emissions and the contribution to global warming. Many people are unaware that the CO2 emissions from peat soils, also known as organic soils, vary a lot within, and between, the fields. Permanent grassland may not always be the best mitigating action for lowering CO2 emissions. READ MORE
