Sulphur is an essential plant nutrient that has important effects on both the yield and quality of crops. The majority of UK soils now require sulphur application to boost protein content, according to AHDB.
In the current revision, main emphasis is on 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 Ltd, CF Fertilisers, Monsanto, Severn Trent Water, United Utilities Water, Wessex Water Services and Yorkshire Water Services.
Dr Sajjad Awan, AHDB resource management scientist, says: “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.”
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, it says.
The amendment sheet and the latest digital versions can be downloaded and are also available as an iBook from www.ahdb.org.uk/rb209.
