  1. 1. Soil compaction and the effect on infiltration in urban green environments : A study based on field measurements and HYDRUS 1D modelling

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Anastasia Novikova; [2023]
    Nyckelord :HYDRUS; surface runoff; soil compaction; urban environments;

    Sammanfattning : The consequences of recent flooding and extreme rain events have highlighted the importance of proper urban planning and preventative measures for storm water management. As cities become more urbanized the significance of permeable surfaces such as parks and other urban green spaces increases which infiltrate the water into the ground. LÄS MER

  3. 2. 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

  4. 3. Soil health on organic farms : linking organic farmer practices to soil health and yield

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

    Författare :Lina Johansson; [2023]
    Nyckelord :organic farming; bulk density; management;

    Sammanfattning : Soil health is a part of the sustainable agriculture which the EU is trying to develop. Organic farming can be one way of working towards more healthy soils. The term soil health can be divided into biological, chemical, and physical aspects of the soil that are necessary to sustain the plants grown. LÄS MER

  5. 4. Biogeochemistry and Peat Properties of Restored Peatlands

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Pelle Belaieff Kronborg; [2022]
    Nyckelord :Drainage; Bulk density; Nitrogen; Carbon; Stable isotopes;

    Sammanfattning : Globally, peatlands comprise the most important soil organic carbon pool storing approximately one third of all terrestrial soil carbon. Drainage can turn peatlands to net sources of carbon dioxide. Peatlands have historically been drained to increase the productivity of agriculture and forestry. LÄS MER

  7. 5. Effekter av markstruktur på tryckutbredning och packningsbenägenhet i åkermark : en jämförande fältstudie mellan konventionellt jordbearbetad åkermark och permanent bevuxen åkermark

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

    Författare :Gabriel Thor; [2022]
    Nyckelord :markpackning; hållfasthet; markstruktur; marktextur; direktsådd; reducerad jordbearbetning;

    Sammanfattning : Att gårdar blir större är en tydlig trend inom det svenska lantbruket. Med det följer även en större efterfrågan på större maskiner och redskap. Denna rationalisering medför en ökad risk för att åkermarken blir kraftigt packad och därigenom skadad, vilket på sikt kan leda till försämrad bördighet. LÄS MER
