  1. 11. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum

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

    Författare :Fayez Altabbaa; [2022]
    Nyckelord :Fusarium graminearum; conidium suspension; hypha agar plug; root architecture traits; root cellar structure traits; shoot traits; genotypes;

    Sammanfattning : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. LÄS MER

  3. 12. A case study of estimating Algal biomass productivity from wastewater treatment facilities in the state of Texas and possible use

    Master-uppsats, KTH/Kemiteknik

    Författare :Gopi Raju Makkena; [2022]
    Nyckelord :Microalgae; Rotating Algal Biofilm RAB ; Flash Hydrolysis; Algal biomass; Biofertilizer; Mikroalger; roterande algbiofilm RAB ; flashhydrolys; algbiomassa; biogödsel;

    Sammanfattning : För att hålla vattendragen och miljön rena, renas avloppsvattnet för att nå ett visst mått innan det släpps ut. Vi gjorde en fallstudie för att utvärdera metoderna som används för att behandla avloppsvatten i tre steg: primär, sekundär och tertiär i delstaten Texas, USA. LÄS MER

  4. 13. Microbial ecosystem analysis of biochar-enriched soil in Kenya using microfluidic soil models

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Erik Karlsson; [2022]
    Nyckelord :Soil microbial ecosystem analysis; Microbe abundance; Microbe foraging; Biochar; Agriculture; Microfluidics; In-situ visualization; Kenya; SoilChip; Soil model; Minor Field Study; Technology and Engineering;

    Sammanfattning : Healthy soil is rich in diverse microbial life, and a healthy microbial ecosystem is crucial for any well-functioning agriculture. Soil microbes are essential for organic decomposition and nutrient recycling in the soil, which make nutrients available for agricultural crops. LÄS MER

  5. 14. Emissions of nitrous oxide associated with frost killed cover crops

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Felicia Olofsson; [2022]
    Nyckelord :Nitrous oxide; cover crops; greenhouse gases; freeze-thaw cycles;

    Sammanfattning : Agriculture is responsible for approximately 80% of anthropogenic emissions of the potent and long-lived greenhouse gas nitrous oxide (N2O). N2O emissions from agricultural soils are characterized by high temporal and spatial variability and often peak in short bursts related to events such as precipitation, fertilization and soil thawing.

  7. 15. Assessment of the Agroecological Potential of Biostimulatory Effects : originating from Effective Microorganisms (EM) in terms of Environmental and Socioeconomic Aspects

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Tania Schwarzer; [2022]
    Nyckelord :effective microorganisms; agroecology; biostimulants; beneficial microorganisms; lactic acid bacteria; bokashi; semi-structured interviews; interpretative phenomenological approach;

    Sammanfattning : Environmental pollution, resource depletion and climate change are related to imbalances in the farming system. Effective microorganisms are seen as a possible solution to these problems. LÄS MER
