  1. 21. 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

  3. 22. Arbuscular mycorrhiza in landrace and modern wheat : its impact on plant performance and how it is influenced by plant breeding and modern cropping practices

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Klara Yngve; [2020]
    Keywords : arbuscular mycorrhiza; landrace varieties; modern cultivars; wheat; conventional cropping systems; organic cropping systems;

    Abstract : Modern agriculture has a negative impact on climate and environment and is challenged by climate change. A transition to a more sustainable, secure and yet high food production is necessary. Landrace cereals attract attention for their ability to sustain nutrient deficiency, drought and harsh climate conditions. READ MORE

  4. 23. 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/Dept. of Plant Breeding (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

  5. 24. Höstgödsling av höstvete med pelleterat rötrestbaserat gödselmedel : en ny källa till växtnäring?

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

    Author : Axel Nilsson; Richard Andersson; [2020]
    Keywords : rötrestprodukt; biogas; NPK; höstgödsling; höstvete; myllning; kväve; fosfor; kalium; skotträkning; EkoBalans KretsloppsNPK ;

    Abstract : Försöket handlar om att jämföra effekten av Ekobalans gödselprodukt (NPK 7-2-5), av pelleterade biogasrester, med YaraMila Raps (NPK 17-5-10), på antal skott i höstvete på våren efter höstgödsling. Innehållet i dessa produkter är snarlika varandra när vi jämför NPKinnehållet i produkterna. READ MORE

  6. 25. Black phosphorous sample preparation for ultrafast electron diffraction studies

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Rebecca Ahrling; [2020]
    Keywords : Graphene; Black phosphorus; electron diffraction; 2D material; Technology and Engineering;

    Abstract : Since 2004 when mechanical exfoliation was first utilised to produce single layered samples of graphite, 2D materials have gained interest in the scientific community. With the prerequisite that the initial bulk material has a layered structure, these 2D materials have created an opportunity to examine materials on a very small scale as well as opening the possibility of creating smaller electrical components for industrial and commercial use, with well-known and documented parameters.
