Enhanced efficiency nitrogen fertilisers in wheat locations
Aims

To test the range of enhanced efficiency nitrogen fertilisers (EENFs) and liquid fertiliser strategies.

Key messages
  • Trial work with Southern Farming Systems over the past four years has demonstrated significant improvements in nitrogen efficiency from applying ENTEC treated urea to wheat crops, compared to untreated urea.
  • The experiment this year showed no response to nitrogen, but did highlight some important tools for predicting the liklihood of nitrogen response.
