Agricultural Management Practices Impact On Soil Carbon and Nitrogen Pools and Soil Quality Dynamics: I

Oral Session

S06 Soil & Water Management & Conservation

This topical session will address the impact of different management practices on soil carbon and nitrogen dynamics, GHG gas emission, and soil quality indicators. The focus will be on the impact of agricultural management practices on soil aggregation, C and N dynamics, greenhouse gas emission, soil bulk density, and soil carbon sequestration just to name few. Emphasis will be given to understanding different management practices effects on soil C and N cycling in agroecosystems as a result of C and N inputs to the soil, their transformation and translocation, and rate of soil carbon sequestration.
