  1. 1. Modelling the Water Table in a Bog

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tobias Bowley; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  3. 2. Nutrient flow on agroforestry farms in the province of Son La in northwest Vietnam

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Vindenergi

    Författare :Tula Strotz; [2023]
    Nyckelord :Agroforestry; contouring grass rows; Guinea grass; nutrient losses; Vietnam; Gräsbarriärer; Höglandsodling; näringsförlust; Träjordbruk; Vietnam;

    Sammanfattning : The population in the high mountains of the northwest provinces of Vietnam belongs to the poorest population in the country. Among the reasons behind this are the high frequency of minority groups in the region and the infertile soils of the steep slopes. LÄS MER

  4. 3. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Yixian Chen; [2023]
    Nyckelord :density; ground vegetation; height; stem radial growth; legacy nitrogen effect; soil total N and C N ratio; tree;

    Sammanfattning : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. LÄS MER

  5. 4. The effects of management practices and environmental variables on the biodiversity of Nardus grasslands in the national park Hohe Tauern, Austria

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Rebecca Paulina Dörner; [2023]
    Nyckelord :biodiversity; Nardus stricta; Nardus grassland; national park Hohe Tauern; East Tyrol; alpine pastures;

    Sammanfattning : Introduction. A large part of the biodiversity of the Alps is linked to an interaction between the natural environment and traditional land-use practices. This study focuses on the priority habitat type of species rich Nardus grasslands (Natura 2000 Code 6230*), which is endangered, but continues to thrive in extensively managed subalpine pastures.

  7. 5. Nodulation and biomass development of yellow and blue lucerne under pH stress

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Katarina Boström; [2023]
    Nyckelord :lucerne; blue lucerne BL ; yellow lucerne YL ; E. meliloti; nodulation; pH;

    Sammanfattning : Approximately 77% of global arable land use is devoted to forage cultivation, which is the basis for animal production and global food security. Therefore a sustainable and biologically diverse forage cultivation is needed. Feed for cattle needs to contain a good balance between fibre, energy and protein. LÄS MER
