  1. 1. Effect of Mycorrhizal Inoculation on Growth and Nutrient Uptake by Leek (Allium porrum) fertilized with Inorganic N Combined with Saturated Polonite

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

    Author : Emmanuel Owusu Boateng; [2023]
    Keywords : Phosphorus; Arbuscular Mycorrhiza fungi; Saturated polonite; Nitrogen; Allium porrum; Sustainability; circular economy;

    Abstract : The continuous rise in global population continues to increase the demand for food. Meeting this rise in demand requires an increase in agricultural input, such as applying fertilizers, including phosphorus (P). READ MORE

  3. 2. Nodulation and biomass development of yellow and blue lucerne under pH stress

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Katarina Boström; [2023]
    Keywords : lucerne; blue lucerne BL ; yellow lucerne YL ; E. meliloti; nodulation; pH;

    Abstract : Approximately 77% of global arable land use is devoted to forage cultivation, which is the basis for animal production and global food security. Therefore a sustainable and biologically diverse forage cultivation is needed. Feed for cattle needs to contain a good balance between fibre, energy and protein. READ MORE

  4. 3. Non-Destructive Biomass and Relative Growth Rate Estimation in Aeroponic Agriculture using Machine Learning

    University essay from Lunds universitet/Matematik LTH

    Author : Oskar Åström; [2022]
    Keywords : Machine Learning; Image Analysis; Aeroponics; Hydroculture; Relative Growth Rate; Multi-variate Regression; Neural Network; ResNet; Plant Growth; Plant Physiology; Technology and Engineering;

    Abstract : Optimising plant growth in a controlled climate requires good measurements of both biomass (measured in grams) and relative growth rate (measured in grams of growth per day and gram of plant). In order to do this efficiently and continuously on an individual level during plant development, this has to be done non-destructively and without frequent and labor intensive weighing of plant biomass.

  5. 4. In-vivo imaging of root growth in response to localized mechanical stress

    University essay from SLU/Dept. of Soil and Environment

    Author : Leah Eitelberg; [2022]
    Keywords : kinematics analysis; time-lapse imaging; root growth rate; root curvature; soil heterogenety; local mechanical stress;

    Abstract : By taking up nutrients and water, root growth has an important influence on plant growth and productivity. Thereby, root growth is influenced by its surrounding soil conditions, which vary spatially even on a small scale. Hence, different parts of the root system are exposed to different penetration resistances in the soil. READ MORE

  6. 5. Erosionens naturliga skydd : växtens egenskaper och inverkan på yterosionsbildning vid slänter

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Felix Dahlbäck; [2021]
    Keywords : erosion; ; yterosion; slänter; ingenjörsbiologi; water erosion; erosion control; vegetation coverage;

    Abstract : Vårt landskap utsätts hela tiden för förändringar, där både naturliga processer och mänsklig påverkan kan orsaka stora problem. Erosion är en naturlig process men kan påskyndas av människliga aktiviteter, markanvändning och klimatförändringar. READ MORE
