Nitrogen

Study reveals how discharge and residence time control nitrogen cycling in tidal freshwater zones, with denitrification dominating during low-flow periods and implications for managing estuarine.

Nitrogen topdressing timing regulates basal internode structure and mechanical properties in winter wheat, improving lodging resistance by 41.8% and yield by 12.2%.

Study demonstrates drip fertigation increases winter wheat yield 15–21% and improves nitrogen uptake, particularly after flowering, while expanding optimal planting density range.

Elevated CO2 does not enhance nitrogen or phosphorus mobilization in Eucalyptus woodland, suggesting phosphorus limitation stems from scarcity rather than competition.

Adding trace ethylene to nitrogen carrier gas in GC-MS increases sensitivity 20-fold while maintaining 70 eV electron-ionization spectral patterns compatible with existing reference libraries.

Study examines nitrogen-molybdenum interactions in winter wheat, finding that elevated molybdenum under reduced nitrogen enhances yield and nitrogen use efficiency.
