  1. 1. Optimalt pH-värde i åkermark för en effektiv växtproduktion : vilka rekommendationer finns i andra nordeuropeiska länder?

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

    Författare :Kristina Wigfeldt; [2023]
    Nyckelord :mål-pH; kalkning; jordarter; grödor;

    Sammanfattning : En effektiv, lönsam och hållbar växtproduktion vill de flesta lantbrukare i alla länder uppnå. Det är av största vikt att sträva efter ett optimalt pH då det är en variabel som påverkar de flesta kemiska reaktioner och processer i marken. LÄS MER

  3. 2. Legumes as protein-based alternatives to meat: A case study of Färsodlarna and Stacky’s

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hilda Nilsson; [2023]
    Nyckelord :Legumes; Multi-Level Perspective; Plant-Based Products; Sustainable Development; Sustainable Food System; Sustainability Transition;

    Sammanfattning : The urgent action needed to achieve the goals within the Paris Agreement and restrict the increase of global warming to 1,5 degrees calls for adaptation across the whole of society. One way to reduce anthropogenic greenhouse gas emissions is to enable a transition towards a sustainable food system, from meat products to more plant-based products including the consumption of more legumes.

  4. 3. Profitability of optimizing biogas production in dairy farms : an experimental case study of a Swedish dairy farm´s usage of nitrogen in digestate as a nutrient resource for crop production

    Master-uppsats, SLU/Dept. of Economics

    Författare :Nils Hermansson; Albin Åkerblom; [2023]
    Nyckelord :biogas; optimization; profitability; economic effects; organic; conventional; agriculture; dairy farms; digestate; nitrogen; biogas; optimering; lönsamhet; ekonomiska effekter; ekologiskt; konventionellt; lantbruk; mjölkgårdar; rötrester; kväve;

    Sammanfattning : Biogas has the potential to be a contributor to sustainable energy for electricity, fuel, and heating. Because of that, there are different alternatives for biogas plants. In this study, a farm-based biogas plant for electricity production has been of interest. LÄS MER

  5. 4. Arable Plant Diversity on Gotland, Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Rebecca Örnberg; [2023]
    Nyckelord :Arable plant; arable plants; arable diversity; arable; weed diversity; arable weed diversity; arable weed; arable weeds; plant diversity; diversity; drivers of diversity; field size; effects; crop type; standing crop; soil texture; organic farming; diversity; conventional farming; management; herbicides; rare plants; organic; biodiversity; field diversity; field margins; weed survey;

    Sammanfattning : Arable plant species diversity has been on a decline, with many species dependent on arable land becoming threatened. At the same time, attempts at defining the drivers of arable plant diversity have proven difficult and results are often contradictory. LÄS MER

  7. 5. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Alma Fahlén Hammar; [2023]
    Nyckelord :Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Sammanfattning : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.
