Mitigating high fertiliser prices

Past Event

Thursday, 16 December 2021

3:00pm - 4:30pm

Webinar recording

The recent energy crisis has led to unprecedentedly high fertiliser prices well in, with potential for these to rise further before spring 2022.

The high prices mean growers must factor in a new economic optimum to their nutrient management plans, as the point at which the value of extra grain produced is not worth the cost of the extra N applied has shifted considerably.

This webinar will help you judge the economic optimum level of nitrogen to apply to cereals and/or oilseeds crops, accounting for fertiliser and grain prices. The guidance will help suggest potential adjustments to your typical farm nitrogen rates. All information discussed will be based on RB209 fertiliser guidance and recently revised data by ADAS.

Our expert panel will consist of:

  • Pete Berry (ADAS) – understanding your own economic optimum of when to apply nitrogen
  • James Holmes (AHDB) – using RB209 to guide your decision making
  • Mark Topliff (AHDB) – when doesn’t nitrogen pay? Analysis of the Farmbench dataset to understand the most profitable use of fertiliser on UK farms
  • Helen Plant (AHDB) – fertiliser and grain prices - 2022 and beyond?
