  1. 11. Abundance of root nodules on common bean, Phaseolus vulgaris : a comparison between Swedish fields with and without a recent history of common bean cultivation

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

    Författare :Christina Hultman; [2018]
    Nyckelord :sustainability; protein-source; legume-based food; nitrogen fixation; root nodules;

    Sammanfattning : Legumes such as common bean, Phaseolus vulgaris L. are climate-smart protein sources which can be part of sustainable agriculture and eating habits to increase the resilience in our food system. LÄS MER

  3. 12. Forest succession on abandoned agricultural land and its carbon stock

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Parisa Mazinanian; [2017]
    Nyckelord :forest succession; carbon stock; tree species; understorey vegetation; agricultural land abandonment; biomass; secondary forest; old-growth forest; soil carbon; carbon sequestration;

    Sammanfattning : The development of secondary forest on abandoned agricultural lands has proven significant to land cover changes, especially in marginal areas across Europe. It is therefore important to quantify secondary forest succession in order to sustainably manage forest and agricultural resources, and also for modelling climate change. LÄS MER

  4. 13. Klippträda istället för svartträda : icke-kemisk kvickrotsbekämpning i växande gröda

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Crop Production Ecology

    Författare :Erik Bertholtz; [2016]
    Nyckelord :Elymus repens; kvickrot; mekanisk bearbetning; italienskt rajgräs; vitklöver; konkurrens; couch grass; mechanical treatment; Italian ryegrass; white clover; competition;

    Sammanfattning : Kvickrot (Elytrigia repens (L.) Desv. ex Nevski) är ett flerårigt ogräs som är vanligt förekommande i svenska odlingsmarker. Innan kemisk totalbekämpning med glyfosat var kvickrot ett vanligt problem i lantbruket. LÄS MER

  5. 14. A multi-scale based method for estimating coniferous forest aboveground biomass using low density airborne LiDAR data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Jialong Duanmu; [2016]
    Nyckelord :individual tree identification; multi-scale; aboveground biomass AGB ; LiDAR; remote sensing; GEM; Earth and Environmental Sciences;

    Sammanfattning : Forest biomass acts as an important indicator of carbon resources in terrestrial system. Estimation of forest biomass enables a straightforward measurement of carbon storage and provides initial values for process-based carbon cycle models to simulate carbon dynamics. LÄS MER

  7. 15. Finding a method for simplified biomass measurements on Sahelian grasslands

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Elise Palm; [2013]
    Nyckelord :Geography; Physical geography; biomass; grasslands; Sahel; digital camera images; LAI; Earth and Environmental Sciences;

    Sammanfattning : Traditional measurements for determination of aboveground biomass (AGB) are widely used in ecological studies. However, they are labor demanding and time consuming, why this study performed on a grassland in Senegal has focused on finding a simplified AGB estimation method that could be applied on larger areas in the Sahel.
