The Role of Soil Management in Influencing Nitrous Oxide Emissions and Microbial Processes

Oral Session

S03 Soil Biology & Biochemistry

The role of soil management on soil processes such as leaching, GHG emissions and microbial nutrient transformation will be examined. Factors such as tillage, fertilization, crop rotation influence on microbial processes will be emphasized. The role of soils in mitigating climate change will also be included.
