  1. 1. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands

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

    Författare :Richard Engholm; [2024]
    Nyckelord :chronosequence; soil respiration; total respiration; autotrophic respiration; heterotrophic respiration; forestry;

    Sammanfattning : How the forests in Sweden and around the world have been, and are still today, managed is a hot debate. The rotation forestry that is commonly used in Sweden has been the focus of debate regarding whether it is a sustainable management method, and whether it should be changed. LÄS MER

  3. 2. The influence of soil management on soil health : an on-farm study

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

    Författare :Hanna Williams; [2018]
    Nyckelord :crop diversity; soil health assessment; indicator; soil quality; ecosystem services;

    Sammanfattning : The capacity of a soil to provide ecosystem services without negative impacts on the environment is defined as soil health. Healthy soils are a fundamental resource for agricultural production and our ability to feed a growing global population. We must therefore increase our understanding of how soil health is affected by soil management. LÄS MER

  4. 3. Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Hanna André; Agnes Bondesson; [2014]
    Nyckelord :klimatförändringar; växthuseffekten; boreal skog; fotosyntes; markrespiration; koldioxid; marktemperatur;

    Sammanfattning : During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today.

  5. 4. Temperaturens och den fotosyntetiskt aktiva strålningens effekt på avgång och inlagring av kol på en dikad torvjord

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Kristian Österlund; [2013]
    Nyckelord :torv; markrespiration; NEE; fotosyntes;

    Sammanfattning : The decomposition of organic carbon in drained peat soils is a major source of carbon di-oxide in Sweden. A big part of these drained peat soils are used in agriculture and it is a big challenge to slow down their decomposition. LÄS MER

  7. 5. Spatial heterogeneity of soil CO2 efflux at ADVEX site Norunda in Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Bahzad Khaled; [2011]
    Nyckelord :soil CO2 efflux; spatial variation; depth of the soil; humus thickness; micro topography; stand and forest floor characteristics; mark-CO2-utflöde; rumslig variation; markdjup; humustjocklek; mikrotopografi; trädbestånd; skogsmarkskaraktäristik; Earth and Environmental Sciences;

    Sammanfattning : This study investigates the spatial variation in soil carbon dioxide (CO2) efflux in a boreal mixed forest mainly dominated by Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L.) in the ADVEX expermental site in Norunda, in central Sweden. LÄS MER
