Soil archaeal and bacterial amoA amplicon sequencing

Nitrification plays a central role in the global nitrogen cycle, which is affected by interaction between soil microfauna and microorganisms. The impact of synchronized changes of nematodes and ammonia-oxidizers within aggregate fractions on nitrification was investigated under 10-year manure application in an acid soil. Nematodes, ammonia-oxidizers, and potential nitrification activity (PNA) were examined within three aggregate size fractions from soils under four fertilization regimes.
