  1. 1. The potential use of black soldier fly larvae residue as a fertilizer

    Master-uppsats, SLU/Dept. of Agricultural Biosystems and Techology

    Författare :An-Marthe Ingelaere; [2023]
    Nyckelord :organic waste; fertilizer; black soldier fly; residue; physico-chemical characteristics; sub-Saharan Africa; socio-economic constraints;

    Sammanfattning : In sub-Saharan Africa (SSA), the primary constraint of agriculture productivity has consistently been ascribed to soil fertility. A common approach to improve soil fertility is the use of fertilizers, both organic and inorganic. Though recently interest is increasing in the use of newer alternatives like biostimulants. LÄS MER

  3. 2. The carbon footprint of rye bread production in Sweden : a life cycle assessment (LCA) of the Fazer product Rågkusar

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Stella Hildersten; [2023]
    Nyckelord :Life Cycle Assessment LCA ; bread; rye bread; bread production; sustainable development; carbon footprint; global warming potential;

    Sammanfattning : The future will require sustainable food systems; systems that meets the present and the future with consideration of economic and social development, as well as environmental protection. In the current food system, two key drivers towards environmental pressure are agriculture and food consumption. LÄS MER

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

    Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

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

    Sammanfattning : 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.

  5. 4. Farmers Coping with Market Shock : a multiple case study of Agricultural SMEs

    Master-uppsats, SLU/Dept. of Economics

    Författare :Jesse Harder; [2023]
    Nyckelord :agriculture; market shock; crop farms; risk management; resilience; decision-making; adaptation; price volatility; coping strategies; market uncertainty; Ukraine war;

    Sammanfattning : This research explores how agricultural SMEs are coping with the agricultural market shock mainly caused by Russian-Ukraine war outbreak in February 2022. The research paper is guided by three research questions investigating 1) the impacts of the current market shock on farms, 2) the coping strategies and decisional motivation of farmers, and 3) the planned adaptations and learnings of the farmers.

  7. 5. Companion crops in winter oilseed rape : effects on nitrogen concentration, biomass, and prevalence of weeds at the end of autumn growth

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Stina Johansson; [2023]
    Nyckelord :biomass; companion crops; intercropping; legumes; nitrogen concentration; organic cultivation; weeds; winter oilseed rape;

    Sammanfattning : Intercropping can be used as a management system to promote higher yield as well as less weeds,diseases, and insect damage. Legumes are a commonly used companion crop (CC) in intercropping due to the benefit of nitrogen (N) fixation. LÄS MER
