1. Nitrogen cycling communities associated to roots of arable crops in relation to management : plant, intercropping and soil effects
Sammanfattning : Management of terrestrial nitrogen (N) has been identified as a key challenge in the implementation of sustainable agricultural practices. Transformations of inorganic N are mainly performed by microbial functional guilds that regulate the retention or loss of N. LÄS MER
2. Nutrient supply to reed canary grass as a bioenergy crop : intercropping and fertilization with ash or sewage sludge
Sammanfattning : Production of renewable energy from herbaceous crops on agricultural land is of great interest since fossil fuels need to be replaced with sustainable energy sources. Reed canary grass (RCG), Phalaris arundinacea L. is an interesting species for this purpose. LÄS MER
3. Nutrient supply to reed canary grass as a bioenergy crop : intercropping with legumes and fertilisation strategies for phosphorus and potassium
Sammanfattning : Growing energy demand and global warming are promoting research into potential new sources of renewable energy. Fossil fuels need to be replaced with sustainable energy sources to decrease emissions of greenhouse gases. Production of bioenergy from herbaceous crops on agricultural land is one alternative.

4. Leguminous service crops in cereal production at high latitudes : provision of ecosystem services and disservices from a novel intercropping system
Sammanfattning : Service crops, crops grown to provide services such as soil protection, weed control, or nutrient capture and provision, can reduce the need for mineral fertilisers and intensive weed control. However, high biomass production is necessary in order for these services to be provided. This can be difficult to achieve at high latitudes (e.g. LÄS MER
5. Growth and nitrogen economy of cereal-legume sole- and intercrops, and their effects on weed suppression
Sammanfattning : Crop production currently faces the dilemma of using methods that increase crop yield but with adverse environmental effects, or attaining lower yields with less environmental impacts. Applying ecological principles has shown potential in finding a middle-ground of maintaining crop yield with less inputs. LÄS MER
