  1. 16. Biokol i substratblandningar : möjlighet för plantskolenäringen att minska användning av torv

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

    Author : Annika Svensson; [2022]
    Keywords : biokol; substrat; vattenhållande förmåga; torr skrymdensitet; kompaktdensitet; porositet; containerodling; Air-Pot; Ulmus laevis; Fagus sylvatica fk GOTTÅSA E;

    Abstract : Genom att använda andra typer av material för substratblandningar till odling av träd och buskar i plantskolenäringen kan man minska användningen av torv. I detta självständiga arbete har olika material använts till försök för att se möjligheter till att hitta alternativ till delar i ett, ur växtens synpunkt, bra substrat. READ MORE

  3. 17. 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

  4. 18. The effect of high-ratio biochar replacement in concrete on performance properties : Experimental study of biochar addition to concrete mixture.

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand
