  3. 2. 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
