  1. 1. N2 fixation of three legume species in an agroforestry system

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Hsiang-Ju Fan; [2023]
    Nyckelord :nitrogen; dinitrogen fixation; legumes; groundnut; stylo; pinto peanut; understorey crop;

    Sammanfattning : Due to the strong soil erosion caused by agricultural activities and sloping landscape, agroforestry has been introduced as a potentially sustainable cropping practice in the mountainous NW Vietnam. Using legumes as understorey crops in these systems has a potential to limit erosion and smother weeds, as well as provide additional nitrogen (N) to the system. 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. Nitrogen fixation in wheat (Triticum aestivum) : effect of Azotobacter salinestris CECT 9690 on N-accumulation

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :John Pålsson; [2023]
    Nyckelord :Biostimulants; Vixeran; N-uptake; N-concentration; yield; cereals;

    Sammanfattning : Biostimulants are products that can improve nutrient availability, nutrient uptake, nutrient use efficiency and tolerance to abiotic stress with the aim to increase plant growth and yield. During the last decades, the interest in, and market for biostimulants has grown and is expected to have a large compound annual growth rate. LÄS MER

  5. 4. Modeling and simulation of existing biogas plants with SIMBA#Biogas

    Master-uppsats, Linköpings universitet/Teknisk biologi

    Författare :Jonas Karlsson; [2017]
    Nyckelord :Biogas; SIMBA#Biogas; Anaerobic digestion;

    Sammanfattning : The main purpose of this project was an attempt to modulate and simulate two existing biogas plant, situated in Lidköping and Katrineholm, Sweden and evaluate how the process reacts to certain conditions regarding feeding, layout and substrate mixture. The main goal was to optimize the existing processes to better performance. LÄS MER

  7. 5. Soil factors affecting plant performance of climbing beans (Phaseolus vulgaris L.) in south western Kenya

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Hanna Williams; [2016]
    Nyckelord :penetrometer; resistance; soil pH; staking; CN ratio; Kisii; KALRO;

    Sammanfattning : The south west part of Kenya is the most densely populated part of Kenya. This part of Kenya has relatively fertile soils and a favorable environment for crop production, which is why it is a major food producing area. The high population results in land scarcity with the average farm size ranging from 0.8-1. LÄS MER
