  1. 26. Effects of nitrogen quality and quantity on weed-crop competition : a greenhouse experiment with Avena sativa and Avena fatua

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Crop Production Ecology

    Författare :Lukas Hallberg; [2019]
    Nyckelord :weed-crop competition; resource pool diversity; soil microbes; weed community;

    Sammanfattning : The intensification of agricultural activities has provided unprecedented increases in crop production. In the light of this development concerns have been raised about its negative environmental impact. High-input farm management has further reduced the weed diversity and shaped weed communities to consist of a few highly competitive weed species. LÄS MER

  3. 27. How do African ElephantsUtilize the Landscape DuringWet Season? : A Habitat Connectivity Analysis for Sioma Ngwezi Landscape in Zambia

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Nyckelord :;

    Sammanfattning : How environmental factors influence distribution and persistence of African elephants(Loxodonta africana) is pertinent to policy makers and managers to formulate balanced plansfor different landuse types (i.e. wildlife management, forestry). LÄS MER

  4. 28. Analysing the vegetation condition during the 2017 and 2018 growing seasons using indices derived from Sentinel-2 data : a case study over southern Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Camilla Persson; [2019]
    Nyckelord :Physical Geography and Ecosystem analysis; remote sensing; vegetation indices; drought; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : The summer of 2017 was climatically close to normal in southern Sweden, whereas the following summer was unusually warm and dry. These two years therefore make an interesting case study for investigating the impact of severe drought on vegetation, particularly when considering that climate change is predicted to lead to an increased frequency of drought events in the study area.

    Sammanfattning : To reduce pesticides and find greener alternatives for weed management in crop production has been a big issue worldwide. In Sweden, the Board of Agriculture has developed grants for farmers who use e.g. cover crops and new and greener strategies (e. LÄS MER

  7. 30. Design of an Autonomous Weeding Vehicle

    Master-uppsats, Lunds universitet/Innovation

    Författare :Simon Axbom; Lisa Ralsgård; [2019]
    Nyckelord :Mechanical Engineering; Product Development; Agricultural Robotics; Weeding; Lightweight Vehicle; Technology and Engineering;

    Sammanfattning : This thesis describes the development of an autonomous weeding vehicle for the agricultural industry. It has been done as a project at RMIT University in Melbourne and the aim was to develop a design for the vehicle which could later be used to develop a commercial product. LÄS MER
