Technical Note (TN731): Nitrogen Recommendations for Cereals, Oilseed Rape and Potatoes

Summary

  • Nitrogen recommendations for cereals and winter oilseed rape include an adjustment for expected yield.
  • Nitrogen recommendations for potatoes take account of length of growing season, variety group, soil N residues and haulm killing.
  • New trials suggest that there is no advantage to a split application of nitrogen to potatoes compared with all nitrogen applied at planting.
  • Take account of fertiliser nitrogen and crop produce prices.
  • Nitrogen recommendations take account of NVZ Action Programme rules and Nmax.
  • Careful planning that maximises the efficient use of fertiliser and organic materials can help reduce the amount of N that is lost as nitrous oxide, a greenhouse gas.
