  1. 1. Platsens betydelse för växtnäringsläckage från jordbruksmark i Sverige

    University essay from SLU/Dept. of Soil and Environment

    Author : Frida Lundell; [2023]
    Keywords : kväve- och fosforutlakning; rumslig variation; långtidsövervakning;

    Abstract : Växtnäringsläckage av kväve (N) och fosfor (P) från jordbruksmark tillför näringsämnen till hav och vattendrag. Det är viktigt att minska transporten av N och P av flera anledningar, då det bland annat är en stor bidragande faktor till övergödning. READ MORE

  3. 2. Mussel farming along the south-Swedish coasts - a possible solution to eutrophication?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : David Trulsson; [2023]
    Keywords : Mussel farming; Aquaculture; Spatial suitability analysis; Eutrophication; Baltic Sea; Biology and Life Sciences; Earth and Environmental Sciences;

    Abstract : The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. READ MORE

    University essay from SLU/Dept. of Soil and Environment

    Author : Lovisa Nissen; [2022]
    Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

    Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE
