Som skogsägare kan man prioritera vilka värden man vill gynna i sin skog; ekonomiska, sociala och/eller biologiska. LÄS MER

  3. 2. 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

    Nyckelord :density; ground vegetation; height; stem radial growth; legacy nitrogen effect; soil total N and C N ratio; tree;

    Sammanfattning : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. LÄS MER
