Best Management Practices – Timing of Nutrients

Quick fact sheet to support application timing of nitrogen to maximize efficiency.

  • Application timing is the Right Time in 4R nutrient management.
  • Splitting nutrients into at least two applications better matches plant growth and nutrient uptake rates.
  • Timing of nutrient application close to or within the growing season increases uptake efficiency.
  • Delayed application of N can allow for rate adjustment based upon growing season conditions and yield projections.
  • Avoid application before precipitation and irrigation events.
  • Split application of N is most suitable on loamy sands, sandy loams and situations with shallow groundwater.
