  1. 1. Högfrekventa mätningar med sensorer för transportberäkning av totalfosfor i vattendrag

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Nora Ottander; [2020]
    Keywords : turbiditet; fosfor; sensor; transportberäkning; övergödning;

    Abstract : Large areas in the Baltic Sea suffer from eutrophication, due to excessive input of nutrients, mostly nitrogen and phosphorus, from surrounding coasts. The transfer of phosphorus is mostly riverine. READ MORE

  2. 2. The effect of Arbuscular mycorrhizal fungi and biostimulating algae extract on establishment, growth and development of Vitis vinifera : a field study conducted in Sweden

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

    Author : Hanna Silwer; [2020]
    Keywords : Arbuscular mycorrhiza; biostimulator; crop physiology; mineral fertilizers; precision farming; Vitis vinifera;

    Abstract : About 23% of total global net anthropogenic emissions of greenhouse gases (GHG) come from agricultural and forestry related activities. One of the largest contributors of GHG is the usage of nitrogen (N) and phosphorous (P) fertilizers, causing eutrophication and contributing to global warming. READ MORE

  3. 3. Effekter av klimatförändringar på växtplankton i subarktiska och alpina sjöar

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Matilda Lundström; [2019]
    Keywords : Fosfor; Växtplanktonbiomassa; Diversitet; Oligotrofiering; Temperatur;

    Abstract : The aim of this report was to determine how the climate change affects the ecosystems in alpine and subarctic lakes in Sweden. This was done by analyzing data from environmental monitoring of 14 subarctic and alpine lakes that was part of the national time-series lake monitoring program. READ MORE

  4. 4. Investigation into Melting Characteristics of Hydrogen-Reduced Iron Ore Pellets

    University essay from KTH/Materialvetenskap

    Author : Hedda Pousette; [2019]
    Keywords : Iron Ore Pellets; Sulphur; Phosphorous; Slag; Hydrogen Gas; Järnmalmspellets; Svavel; Fosfor; Slagg; Vätgas;

    Abstract : What kinetic and thermodynamic characteristics are established in a melt of hydrogen-reduced iron ore pellets? The pellets contain self-fluxing slag components which upon melting form an initial slag. Refining capabilities of this slag, such as dephosphorization power, are investigated in a lab-scale vertical furnace. READ MORE

  5. 5. Analysis of the distribution of plant nutrients in a biogas production system : a look at VH Biogas, co-digesting manure from several farms

    University essay from SLU/Dept. of Soil and Environment

    Author : André Johansson; [2019]
    Keywords : biogas; digestate; manure; nutrients;

    Abstract : This study examined nutrient flows in a system where 20 farms deliver manure to a biogas plant for digestion, and then receive digestate back. Some other substrates were also anaerobically digested at the plant e.g. slaughter residues. READ MORE
