  1. 1. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Shahin Shamim; [2023]
    Nyckelord :Sewage Sludge-Phosphorus-Pyrolysis- Heavy metals; Cadmium; Lead; Nickle; Copper; Chromium; Zinc; Biochar; Heating value; Fertilizer- Thermal conversion;

    Sammanfattning : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. LÄS MER

  3. 2. Companion crops in winter oilseed rape : effects on nitrogen concentration, biomass, and prevalence of weeds at the end of autumn growth

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

    Författare :Stina Johansson; [2023]
    Nyckelord :biomass; companion crops; intercropping; legumes; nitrogen concentration; organic cultivation; weeds; winter oilseed rape;

    Sammanfattning : Intercropping can be used as a management system to promote higher yield as well as less weeds,diseases, and insect damage. Legumes are a commonly used companion crop (CC) in intercropping due to the benefit of nitrogen (N) fixation. LÄS MER

  4. 3. REINDEER GRAZING IN A NORTHERN BOREAL FOREST : Seasonal and reindeer-induced changes in nutrient availability and soil temperature

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Agnes Karlsson; [2023]
    Nyckelord :nutrient availability; soil temperature; reindeer grazing; seasonal nutrient cycling; boreal forest;

    Sammanfattning : Soil nutrient availability is a key component to understanding the boreal ecosystems, as it directly relates to plant productivity and ecosystem diversity. There is however little known about how the nutrient availability changes seasonally in the boreal forest. LÄS MER

  5. 4. Optimizing nitrogen fertilization in ley : Evaluating the usage of N-sensor and other tools for optimized nitrogen fertilization

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

    Författare :Johan Johnsson; [2023]
    Nyckelord :nitrogen efficiency; optimized fertilization; SN value; unfertilized area; Yara N-sensor;

    Sammanfattning : Nitrogen is an essential nutrient for plant growth. It has several functions in the plant and a lack of nitrogen can cause severe yield losses. LÄS MER

  7. 5. 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
