In the nitrogen-limited soils of Grændalur valley on Iceland, thaumarchaea dominated the process of ammonia oxidation. Ammonia-oxidizing betaproteobacteria came only to the fore in microcosms after addition of ammonium.

Since this nitrogen-limited situation in the field might be due to the relatively young geological age of its subsurface, grassland soils situated on a subsurface of different geological age will be analyzed for the presence of ammonia-oxidizing thaumarchaea and betaproteobacteria.
