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.
