1. 1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Linnéa Eriksson; [2023-04-20]
   Nyckelord :soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

   Sammanfattning : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. LÄS MER

3. 2. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Tsai-wei Tang; [2022-01-26]
   Nyckelord :N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

   Sammanfattning : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. LÄS MER
