  1. 1. Microbial strains from compost originated from circulated side streams : impact on root growth and root hairs

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Benjamin Pettersson; [2023]
    Keywords : Spent Mushroom Compost; Circulated side streams; Botrytis cinerea; Circular Bioeconomy; Soil health;

    Abstract : Spent mushroom compost, apple waste and other organic waste materials are of great potential to improve soil health, water holding capacity and to supress plant pathogens. Today compost is used in apple orchards as an additional fertilizer or soil amendment. READ MORE

  3. 2. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Ellen Ek Moreau; [2023]
    Keywords : Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

    Abstract : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.

  4. 3. Ammonium and nitrate sorption by biochar

    University essay from SLU/Dept. of Soil and Environment

    Author : Yasser Alrhban; [2023]
    Keywords : biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

    Abstract : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

  5. 4. Biochar from separated digestate and pig manure as soil amendment

    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

  6. 5. Phytoremediation potential for poly- and perfluoroalkyl substances (PFASs) using various plant species

    University essay from SLU/Dept. of Aquatic Sciences and Assessment
