  1. Hydrology strongly controlled nitrate cycling in a tidal freshwater river
    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.
  2. Nitrogen split ratio improved lodging resistance and yield in winter wheat
    Nitrogen topdressing timing regulates basal internode structure and mechanical properties in winter wheat, improving lodging resistance by 41.8% and yield by 12.2%.
  3. Drip fertigation improved wheat nitrogen uptake and yield stability
    Study demonstrates drip fertigation increases winter wheat yield 15–21% and improves nitrogen uptake, particularly after flowering, while expanding optimal planting density range.
  4. Elevated CO2 did not alter soil nitrogen or phosphorus mobilization
    Elevated CO2 does not enhance nitrogen or phosphorus mobilization in Eucalyptus woodland, suggesting phosphorus limitation stems from scarcity rather than competition.
  5. Trace ethylene boosts nitrogen GC-MS sensitivity
    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.
  6. High molybdenum with low nitrogen improved wheat yield-related measures
    Study examines nitrogen-molybdenum interactions in winter wheat, finding that elevated molybdenum under reduced nitrogen enhances yield and nitrogen use efficiency.
