  1. 1. Soil Carbon Stocks in Old Growth Forest : Drivers of variability in soil organic carbon stocks in old growth boreal forests

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Elis Ingvarsson; [2023]
    Keywords : old growth forest; boreal; soil organic carbon stocks; climate gradient;

    Abstract : Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems, which plays an important role in climate change by regulating atmospheric carbon dioxide. Sweden’s forest management has led to a decrease in old growth forests. This change in land use can affect SOC levels in these forests. READ MORE

  3. 2. En hållbar kompost : förutsättningar på Habo gård

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Axel Stålhammar; [2023]
    Keywords : hållbarhet; kompostering; komposteringssystem; parkslide; Reynoutria japonica; kol kväve-kvot; lokal hantering av näringsämnen;

    Abstract : Den här kandidatuppsatsen är gjord för att ta reda på ifall det är möjligt att skapa en hållbar kompost på Habo gård. Därtill finns stora mängder organiskt material som inte utnyttjas på Habo gård i näringskretsloppet. READ MORE

  4. 3. Combining GHG Emissions and Soil Carbon Changes as a Single Metric to Evaluate Agricultural Policy Promoting Biomass for Biofuels

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Malin Lane; [2022]
    Keywords : Gräsvallar; klimatpåverkan; kolinlagring; jordbruk; biomassa; biobränslen.; Earth and Environmental Sciences;

    Abstract : Incorporating a multi-year grass ley into an arable crop rotation can increase soil organic carbon stocks, reduce carbon emissions and provide feedstock for biogas. This thesis set out to study how a policy promoting agricultural biomass for biogas impacts GHG emissions and carbon sequestration on a regional level over a temporal scale of 20 years. READ MORE

  5. 4. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping

    University essay from SLU/Dept. of Ecology

    Author : Khadija Aziz; [2022]
    Keywords : cover crops; nitrous oxide; C sequestration; greenhouse gases; off-season emissions; freeze-thaw cycles;

    Abstract : More than 60% of anthropogenic nitrous oxide (N2O) emissions are attributed to agricultural activities. N2O production in soils highly depends on the N availability along with other factors such as soil moisture content, which provide suitable conditions for nitrification and denitrification.

  6. 5. Modelling the impacts of organic matter quality on soil carbon turnover and storage : continued testing of a novel dual-pore model against data collected from a long-term study site in Offer, Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Mikael Sasha Dooha; [2021]
    Keywords : soil; soil organic matter; carbon; carbon sequestration; tillage; land-use; soil structure; porosity; modelling; humification;

    Abstract : As we look for solutions to the worsening climate crisis, carbon sequestration has become a popular strategy to mitigate CO2 emissions. Carbon models are used to predict or emulate changes in future soil organic carbon (SOC) stocks, but most fail to account for the influence of pore size on soil structure and SOC storage. READ MORE
