11. Nutrient and Organic Matter Dynamics in Beech Forest Floors, in Relation to the Presence of Ground Flora
Sammanfattning : The objective of this thesis was to quantify differences between adjacent patches with and without ground flora of Deschampsia flexuosa L. Trin or Anemone nemorosa L. in two acid European beech (Fagus sylvatica L.) forest floors in south-west of Sweden. LÄS MER
12. Plant-based biogas production for improved nutrient management of beetroot in stockless organic farming
Sammanfattning : Transition from a nutrient management system based on green manure (GrM system) to one based on biodigested plant material produced within the crop rotation (BG system) was investigated in crop sequences including clover-grass, beetroot and cereals. The overall hypothesis was that transition would improve nitrogen (N) availability. LÄS MER
13. Soil nitrogen fluxes and root uptake in the boreal forest : key processes to plant nitrogen nutrition
Sammanfattning : Nitrogen (N) is essential for growth and net primary production of plants. However, N acquisition by plants is influenced by movement of soil N compounds from bulk soil to plant roots and uptake of N by roots. This thesis is aimed at deepening our knowledge on these key processes involved in plant N acquisition in the N-limited boreal forest. LÄS MER
14. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi
Sammanfattning : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. LÄS MER
15. External Mycelia of Mycorrhizal Fungi - responses to elevated N in forest ecosystems
Sammanfattning : Most plants live in symbiosis with mycorrhizal fungi. Mycorrhizal roots constitute the interface between the plant and the soil, and almost every fine root of forest trees in nitrogen-limited boreal and temperate forests is colonised by ectomycorrhizal (EM) fungi. LÄS MER
