422 Management Impacts on Soil Properties and Soil C and N Dynamics: II

Oral Session
SSSA Division: Soil & Water Management & Conservation
This session will focus on the impact of management practices on soil properties, aggregation, and C and N dynamics as a result of C and N inputs to the soil, their transformation and translocation in the soil profile, sequestration as aggregate-associated C and N, particulate organic matter (POM), and losses as water soluble or greenhouse gas emission, wind and water erosion, and other processes. This session will strengthen our knowledge on the impact of management practices on soil quality and productivity, C and N balance, and N use efficiency.
