Nitrous oxide (N2O) is emitted from agricultural soils as a product of biotic pathways of the nitrogen (N) cycle. Agricultural practices may affect soil water content, temperature and N availability, and consequently N2O emissions. Thus, it is necessary to identify strategies to mitigate N2O emissions while maintaining crop yields. This two-year st...
Conference Paper
A challenge for agriculture is to individuate strategies to reduce greenhouse gas emissions (GHG) from soil while preserving crop yield. Agricultural practices are reported to affect carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) emissions from soil due to their effects on nutrient cycling and soil conditions (e.g. soil water content,...
