425 Nitrification: New Players and Environmental Drivers: II

Poster Session
SSSA Division: Soil Biology & Biochemistry
The role of ammonia oxidizing bacteria in mediating the first and rate limiting step of nitrification has been known for many decades while the role of archae is a recent discovery. This poster session will include research on N cycling and nitrification process and communities, including new players of this process.
