  1. 1. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Rasha Kamel; [2023]
    Nyckelord :Apple Waste; Wood Chips; Microbial Content; pH; Pseudomonas; General Bacterial Flora; General Fungal Flora; Electrical Conductivity; Nutrient Content; Bulk Density; Porosity; Water Holding Capacity;

    Sammanfattning : Peat, as a non-renewable growing media, poses environmental concerns due to extraction and decomposition processes, leading to increased greenhouse gas emissions. Alternatives growing media with potential to replace or reduce the use of peat are of great need. LÄS MER

  3. 2. Biochar from separated digestate and pig manure as soil amendment

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

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

    Sammanfattning : 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. LÄS MER

  4. 3. Soil carbon relations in Swedish agriculture : A GIS analysis and literature review of soil characteristics at farm level

    Master-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Christiane Schulze; [2022]
    Nyckelord :Carbon sequestration; Crop yield; Management practices; Soil organic carbon; Soil organic matter; Sweden; northern Europe;

    Sammanfattning : Carbon storage in agricultural soils is an important measure to mitigate climate change. As the soil management techniques can greatly influence the amount of carbon stored in agricultural soils, the influence of different managements was analyzed in a literature review for northern Europe and Sweden.

  5. 4. Effekten av olika brukningsmetoder på kolinlagring i åkermark

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Sanna Magnusson; [2022]
    Nyckelord :Soil organic carbon; SOC; carbon sequestration; soil health; agriculture; arable land; crop production; Sweden; cover crops; no-till; reduced tilling; organic amendments; harvest residues; crop rotation; legumes; perennial crops; agroforestry; combined management practices.; Earth and Environmental Sciences;

    Sammanfattning : Increased carbon sequestration in agricultural land is an important measure to reduce global warming. Since the soil is a large carbon sink, a small change in the soil organic carbon (SOC) stocks can make a substantial difference to the carbon dioxide content in the atmosphere. LÄS MER

  7. 5. Effects of diversified cropping on arthropod communities

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Eira Eksvärd; [2022]
    Nyckelord :carabids; spiders; traits; organic amendments; ley legacy effects;

    Sammanfattning : Även intensiva moderna jordbruk är beroende av ekosystemtjänster som organismer bidrar med såsom biologisk bekämpning av skadedjur. Effekten av biodiversitet på ekosystemprocesser förklaras inte i tillräcklig grad av taxonomisk mångfald, utan beror snarare på mångfalden av funktionella egenskaper bland arterna. LÄS MER
