Kategori: Nitrogenfiksering

Ved biologisk nitrogenfiksering utnytter bestemte mikroorganismer energi fra planter til å fiksere nitrogen fra lufta. Det fikserte nitrogenet kan så benyttes av plantene. Biologisk nitrogenfiksering utføres av enkelte mikroorganismer. De mest kjente er bakterier i slekten Rhizobium. Disse lever på røttene til planter i erteblomstfamilien (belgvekster) og henter sin energi fra plantene. Til gjengjeld forsyner bakteriene plantene med nitrogen.

Dette er Kores temaside for forskning på nitrogenfiksering. Her har vi samlet både norsk og internasjonal forskning, og gruppert forskningen i ulike temaer som er viktige for dem som forsker på fiksering av nitrogen i matjord.

Journal of the Science of Food and Agriculture

The 13th edition of the Journal of the Science of Food and Agriculture includes 14 articles of EUROLEGUME's scientific research in its 'In Focus' section.
In addition to the 14 articles, the 'In Focus' starts off with an editorial on 'Enhancing legume growing through sustainable cropping for protein supply' and a review on 'Cowpea: a legume crop for a challenging environment'.

Preventing and remediating degradation of soils in Europe through Land Care

Soils in the European Union are an essential yet often undervalued and degraded resource. Soils deliver numerous important functions and ecosystem services, including, for example, water and nutrient cycling, biomass and food production, or habitats for species. At the same time, soils are affected by a range of degradation processes, in particular: erosion, floods and landslides, loss of soil organic matter, salinisation, contamination, compaction, sealing, and loss of soil biodiversity (COM 2006).

Legumes for mitigation of climate change and the provision of feedstock for biofuels and biorefineries. A review

| Type artikkel: Publisert studie

Kategori: Belgvekster, Karbonlagring, Matjord, Matplanter, Nitrogenfiksering

Humans are currently confronted by many global challenges. These include achieving food security for a rapidly expanding population, lowering the risk of climate change by reducing the net release of greenhouse gases into the atmosphere due to human activity, and meeting the increasing demand for energy in the face of dwindling reserves of fossil energy and uncertainties about future reliability of supply. Legumes deliver several important services to societies. They provide important sources of oil, fiber, and protein-rich food and feed while supplying nitrogen (N) to agro-ecosystems via their unique ability to fix atmospheric N2 in symbiosis with the soil bacteria rhizobia, increasing soil carbon content, and stimulating the productivity of the crops that follow. However, the role of legumes has rarely been considered in the context of their potential to contribute to the mitigation of climate change by reducing fossil fuel use or by providing feedstock for the emerging biobased economies where fossil sources of energy and industrial raw materials are replaced in part by sustainable and renewable biomass resources.
