Root-derived respiration and nitrous oxide production as affected by crop phenology and nitrogen fertilization

In annual crops, the partitioning of photosynthates to support root growth, respiration and rhizodeposition should be greater during early development than in later reproductive stages due to source/sink relationships in the plant. Therefore, seasonal fluctuations in carbon dioxide (CO₂) and nitrous...
