Abstract

© 2019, Springer-Verlag GmbH Germany, part of Springer Nature. Purpose: The recently discovered complete ammonia oxidizers (comammox Nitrospira) challenged our concept of the whole nitrification process, i.e., ammonia oxidation catalyzed by autotrophic ammonia-oxidizing archaea (AOA) and bacteria (AOB), followed by the oxidation of nitrite to nitrate. However, the relative contributions of different ammonia oxidizers to soil nitrification are poorly understood. Materials and methods: Soil samples were collected from five land use types (i.e., cropland, grassland, bushland, transition land, and forest land) from a subtropical soil in Yunnan Province, Southwest China. The quantitative distribu..
