Session: Nitrification: New Players and Environmental Drivers: II (ASA, CSSA and SSSA International Annual Meetings (2015))

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.

Wednesday, November 18, 2015: 2:30 PM-4:30 PM
