  1. 41. Integrating horticultural and arable crops : a sustainable way to increase vegetable production in Scania?

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

    Författare :Stina Helena Mortensen; [2022]
    Nyckelord :Horticulture; agriculture; vegetables; crop rotation; crop sequence; diversification; integration; ecosystem services; farmers’ attitudes;

    Sammanfattning : Modern arable production is associated with a highly homogenous landscape with few cultivated species and is relying heavily on external chemical inputs. Intensive vegetable production, on the other hand, is associated with environmental costs such as increased risk of nutrient leaching and loss of soil organic matter. LÄS MER

  3. 42. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

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

    Författare :Emma Ryding; [2022]
    Nyckelord :Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Sammanfattning : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. LÄS MER

  4. 43. 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. 44. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping

    Master-uppsats, SLU/Dept. of Ecology

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

    Sammanfattning : 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. LÄS MER

  7. 45. Microbial ecosystem analysis of biochar-enriched soil in Kenya using microfluidic soil models

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Erik Karlsson; [2022]
    Nyckelord :Soil microbial ecosystem analysis; Microbe abundance; Microbe foraging; Biochar; Agriculture; Microfluidics; In-situ visualization; Kenya; SoilChip; Soil model; Minor Field Study; Technology and Engineering;

    Sammanfattning : Healthy soil is rich in diverse microbial life, and a healthy microbial ecosystem is crucial for any well-functioning agriculture. Soil microbes are essential for organic decomposition and nutrient recycling in the soil, which make nutrients available for agricultural crops. LÄS MER
