  2. 11. Comparing effects of endogenous and anthropogenic nitrogen supply on ectomycorrhizal fungi

    Author : Karolina Jörgensen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Boreal forests are characterized by strong nutrient limitation and nitrogen is partic-ularly scarce. Ectomycorrhizal fungi acquire nitrogen from the soil in return for car-bon from their tree host and are, thus, pivotal mediators of carbon and nitrogen cy-cling. READ MORE

  4. 12. Improving our understanding of carbon cycling in agroecosystems by studying δ¹³C signatures in soil carbon stocks and fluxes : results from a Swedish long-term field experiment

    Author : Lorenzo Menichetti; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Soil carbon (C) storage has gained much attention in the past decade due to its potentially huge impact on climate change mechanisms. Particular focus has been paid to possible feedback mechanisms, whether soil can be considered a sink or source of C and how soils can be managed in order to mitigate climate change. READ MORE

  5. 13. Assessment of thermal treatment of trace element contaminated soil

    Author : Désirée Nordmark; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Many contaminated sites in Sweden are characterised by a complex contamination situation with a mixture of organic and inorganic contaminants. For example, wood preservation with creosote, pentachlorophenol and chromated copper arsenate (CCA) has caused this kind of co-contaminated sites. READ MORE

  6. 14. Bioindication and bioremediation of landfill emissions

    Author : Christian Maurice; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : This thesis investigates the use of plants, fungi, and microorganisms to assess and treat landfill gas, leachate and contaminated soils. As landfill emissions can occur over extended time periods, it is a practical strategy to develop passive and economical methods for emission control i.e., requiring little human involvement.

  7. 15. Vanadium in soils : chemistry and ecotoxicity

    Author : Maja Larsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Vanadium is a redox-sensitive metal that is released to soils by weathering and anthropogenic emissions. Swedish metallurgical slags are naturally high in vanadium and used as soil amendments and in road materials. However, understanding of vanadium chemistry and bioavailability in soils is limited.
