47 Soil Biology & Biochemistry: I

Oral Session

SSSA Division: Soil Biology & Biochemistry

This is an oral session for papers on soil biology & biochemistry. The first set of the talks will present research on soil organic matter dynamics and will transition into talks on different topics including research on gas emissions, and the use of new techniques or approaches in our field to better understand the soil biology and biochemistry.
