RB209 updated with new comprehensive advice on sulphur

Updated sulphur management advice for cereals and oilseeds is included in a revised AHDB Nutrient Management Guide (RB209).

An essential plant nutrient, sulphur affects both crop yield and quality. Most UK soils now require additional sulphur to boost protein content – and the update explains sulphur availability from different sources and recommendations under different growing conditions.

The research on sulphur was conducted by ADAS and Rothamsted Research with funding from AHDB, Anglian Water Services, CF Fertilisers UK, Monsanto UK, Severn Trent Water, United Utilities Water, Wessex Water Services and Yorkshire Water Services.

AHDB resource management scientist Sajjad Awan said: “The AHDB concept, when we decided to take management and ownership of RB209, was to continually update so our customers have the latest advice and guidance on crop nutrient management.

“The amendment sheet is inclusive of all changes across the seven sections of RB209, therefore you need only one copy. Those ordering hard copies via AHDB will automatically receive one and if you pick one up at an event, make sure you have the amendment sheet enclosed.”

The AHDB has produced digital versions of all seven sections of RB209. The benefits of using the digital version over the printed copies include automatic updates and alerts, the ability to save notes and easier navigation.

With quick and easy access to videos, information and recommendations from the guide, it is practical for use in the field and will always be the latest version available – plus it’s lighter to carry and doesn’t need an internet connection once downloaded.

This is the second update released for RB209 since the ninth edition was launched in May 2017. Further research already in the pipeline is expected to help develop guidance on crop nutrition with a greater emphasis on produce quality.

Available for iOS and Android devices, the RB209 app can be found by searching for RB209: Nutrient Management on the App Store or Google Play. The amendment sheet and latest digital versions can be downloaded from
