  1. 1. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

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

    Författare :Liliana Marcela Daza Gomez; [2023]
    Nyckelord :nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

    Sammanfattning : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. LÄS MER

  3. 2. Hawk-kite as a scaring method for avian pests in Kenyan rice fields

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Linnea Hollsten; [2023]
    Nyckelord :bird; crop; damage mitigation; pest control; repellent;

    Sammanfattning : The human population is increasing globally, and so are the human-wildlife interactions and conservation conflicts. One source of conservation conflict is the crop damage caused by wildlife. Crop damage is negatively affecting farmers, but also the wildlife due to lethal methods used to reduce the damage. LÄS MER

  4. 3. Att bespruta eller inte bespruta?- En studie om växtskyddsmedels påverkan på pollinatörer i svenska jordgubbsodlingar

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Elin Johansson; [2023]
    Nyckelord :pollinatörer; fungicider; herbicider; insekticider; jordgubbar; växtskyddsmedel; Earth and Environmental Sciences;

    Sammanfattning : This study investigated how pollinators are affected by plant protection products (PPP), what type of PPPs strawberry farmers used and what knowledge they had about these products. To investigate this, a literature review and a survey was conducted. The questionnaire was sent to 70 Swedish strawberry farmers of which 11% participated in the study. LÄS MER

    Nyckelord :By-product; Rapeseed press cake; protein; Food engineering; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : There is significant evidence to suggest that diets that include high levels of meat consumption have negative effects on both the environment and human health. As a result, efforts are being made to identify and characterize more plant-based proteins, such as those found in rapeseed. LÄS MER
