  1. 1. 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. Investigating organic fertilisers’ ability to mineralize during the first month of plant propagation

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

    Author : Sebastan Farkas; [2023]
    Keywords : organic fertilizers; sustainability; mineralisation; nitrification;

    Abstract : There are many forms of organc fertilizers produced and sold in the EU, and it can be difficult to assess which ones are the best in regards of nutrient content and the rate of mineraliztion. Two separate trials were conducted to assess the mineralization rates of three different organic fertilizers, available for private customers, on the Swedish market. READ MORE

  5. 4. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    University essay from SLU/Dept. of Soil and Environment

    Author : Marie Björs; [2023]
    Keywords : Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Abstract : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. READ MORE

  6. 5. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping

    University essay from SLU/Dept. of Ecology

    Author : Khadija Aziz; [2022]
    Keywords : cover crops; nitrous oxide; C sequestration; greenhouse gases; off-season emissions; freeze-thaw cycles;

    Abstract : More than 60% of anthropogenic nitrous oxide (N2O) emissions are attributed to agricultural activities. N2O production in soils highly depends on the N availability along with other factors such as soil moisture content, which provide suitable conditions for nitrification and denitrification. READ MORE
