The long awaited AHDB Nutrient Management Guide, the replacement for the Defra RB209 fertiliser manual, is now available, following its launch at this week’s Grassland & Muck event at Stoneleigh.

It can be downloaded as an interactive digital version or as an app for mobile devices. The Guide offers best practice guidance on applying mineral fertilisers, manures and slurries to crops and grassland. Users can choose information relevant to their enterprise from seven colour-coded sections, each of which can be updated easily to reflect the latest research. The digital versions will be updated automatically, so farmers and growers will always have access to the most recent information. In addition, users can save notes, navigate easily and access videos and recommendations within the Guide. 

The AHDB-led cross-sector UK Partnership for Crop Nutrient Management oversaw the project to revise the Guide, which was last updated in 2010. A consortium of experts from across the UK research community, led by ADAS, delivered the revision. The project cost £98,000 and was supported by in-kind industry funding worth around £200,000.

“This project underpins AHDB activity across a number of sector strategies, demonstrating the pivotal role we play in providing farmers and growers with key tools and information to improve their productivity,” comments AHDB knowledge exchange director Dr Susannah Bolton.

The AHDB Nutrient Management Guide is available on iOS and android. The app can be found by searching the App Store or Google Play for RB209: Nutrient Management. In addition, the Guide can also be downloaded as an iBook from the AHDB website,
