  1. 1. Modelling organic farming systems : is livestock needed for a functioning nitrogen cycle and food production?

    University essay from SLU/Dept. of Energy and Technology

    Author : Franziska Johanna Galler; [2023]
    Keywords : organic farming; livestock; stockless farming; nitrogen cycle; nitrogen use efficiency; nitrogen recycling; nutritional value; human nutrition; food system;

    Abstract : Livestock has always been an integral part of nutrient management on organic farms. Environmental, economic and idieological trends are leading to an increasing specialization of agriculture away from mixed farms with livestock. READ MORE

  3. 2. Do I care: How does the provision of information about the environmental benefits of grain legume cultivation in Sweden influence consumers?

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Kalle Nils Valentin Köster; [2022]
    Keywords : Biospheric Values; Diversity; Grain Legumes; Willingness-to-pay;

    Abstract : Grain legume cultivation is promoted to be beneficial for Swedish agriculture due to grain legumes´ ability to engage in biological nitrogen fixation, function as break-crops in cereal-based cropping systems and a general increase in biodiversity. Furthermore, grain legumes are an important pillar of more sustainable diets. READ MORE

  4. 3. Closed ecological life support systems : cycling of carbon, nitrogen and water

    University essay from SLU/Dept. of Ecology

    Author : Hugo Persson; [2020]
    Keywords : closed ecological system; cycling; closure; life support; biosphere; CEEF; MELiSSA; Biosphere 2; bioregenerative; CELSS; environmental;

    Abstract : Materially closed life support systems containing biological components that provide atmosphere, food and water for a human crew has been investigated for use in space travel since the 1960s. The internal cycling of organic material is the essence of these systems and their design and function is the question at issue for this thesis, which has been conducted as a literature study.

  5. 4. Hur påverkas markvegetationen i boreala skogsekosystem av produktionshöjande åtgärder?

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Nils Bodin; Martin Goude; [2014]
    Keywords : skogsgödsling; gödslingseffekt; hyggeseffekt; kväve; täckningsgrad;

    Abstract : I den boreala vegetationszonens skogar är kväve i regel en tillväxtbegränsande faktor som ofta har en avgörande effekt på markvegetationen. Markvegetationen har betydelse för biologiska processer, biodiversitet och ger ekosystemtjänster. READ MORE

  6. 5. Development of PCR primers for community studies of bacterial hydrogenases in environmental samples

    University essay from SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Author : Ernest Ndobe Ndobe; [2013]
    Keywords : uptake hydrogenase; bacterial community; biological nitrogen fixation; symbiosis;

    Abstract : Soil microorganisms interact with plants in ways that affect nutrient availability, hormonal regulation and often lead to improved plant growth. In the N2-fixing root nodule symbiosis between legume plants and bacteria generally called rhizobia the plant gains access to atmospheric nitrogen. READ MORE
