Nutrient Management Guide (RB209)

The Nutrient Management Guide (RB209) helps you make the most of organic materials and balance the benefits of fertiliser use against the costs – both economic and environmental. The guide explains the value of nutrients, soil and why good nutrient management is about more than just the fertilisers you buy; it can save you money as well as help protect the environment.

RB209 questionnaire

As part of a strategic review of RB209, a simple online questionnaire aims to:

  • Capture how you use the guidance
  • Gather information on what RB209 does well and how it could be improved
  • Indicate the value of delivering more information in RB209 to help you better tailor nutrient management

Feedback collected by 29 February 2024 will inform the next phase of the review.

What is the NUTRI-CHECK NET?

NUTRI-CHECK NET (2023–25) aims to help arable farmers across Europe adopt the most effective nutrient management practices. The EU-funded network will collate nutrient management resources and set up farmer Crop Nutrition Clubs (including in England and Scotland) to evaluate nutrient management practices. Farmers and researchers will also work together to create best practice guidance. ADAS, the UK lead, will collaborate with the project’s National Expert Group for the UK, which comprises farmers, researchers and industry representatives. The group includes Amanda Bennett, who oversees the production of RB209 at AHDB.
