 I am working as a postdoc at this department since September 2009. My major research focus lies on soil nitrogen cycling and the nitrogen nutrition of plants. I am especially interested in estimating the supply rates of nitrogen in soils via diffusion, mass flow and root interception. My future vision is to gain more accurate and reliable information on nitrogen fluxes in soils by monitoring these fluxes in situ.For this purpose I adapted a novel technique based on passive microdialysis sampling to allow the application directly in the field. Further development of this technique will greatly help to improve our understanding on the impact of nitrogen availability on plant performance and ecosystem responses to climate change.Click Read More for Contact Information I am also interested in the interaction and competition effects between plants and soil microorganisms for different available nitrogen sources. I have studied inorganic nitrogen fertilizer effects on plant uptake capacities and microbial community structures in temperate agricultural systems and organic nitrogen uptake patterns of epiphytic tank bromeliads in the Atlantic rainforest in Brazil. In Boreal forest ecosystems, organic nitrogen compounds have been found to be highly abundant and therefore might have a key role in plant nutrition. Currently I am investigating the supply and acquisition rates of different organic nitrogen forms for Boreal forest plants. Peer reviewed publications: Inselsbacher E., Näsholm T.
