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 review and news

We first published RB209 in 2017 in seven sections, following a technical review of its content in 2016.

Since then, it has been annually updated, based on evidence provided by research commissioned by AHDB, in partnership with others.

To ensure RB209 continues to meet the changing needs of levy payers, we are leading the first large-scale strategic review of RB209 since 2016.

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.
