Fixace dusíku v půdách malých lesních povodí v České republice
MICHALČÁKOVÁ, Petra
This bachelor thesis summarises the information about nitrogen fixation with an emphasis on the biological non-symbiotic (free-living organisms) fixation in soil of temperate coniferous forests and it also discusses critical factors, which have an impact on the fixation efficiency. The experimental part evaluates the potential rate of non-symbiotic nitrogen fixation in soil samples from fourteen temperate forest catchments in the Czech Republic. The 15N2-incorporation method was used, complemented by the determination of the quantity of the bacterial nifH gene, which encodes one of the nitrogenase's proteins.
