Investigation of the benefits of specialty nitrogen products and liquid nitrogen options for late application in cereals - Trial 2 locations
Aims
  • To compare in crop protein response to late application of urea, Easy N and dissolved urea in solution.
  • To assess differences in topdress nitrogen response when these products are treated with Agrotain.
Key messages

When topdressing nitrogen late in the season with a view to protein increase, consideration should be given to lower volatility nitrogen products when the likelihood of follow up rainfall is low. This trial supported their use by demonstrating significant protein increases, although this was confounded by significant production increases in response to 30 kgN/ha as granular urea.
