The AHDB has made the latest version of its fertiliser “bible”, the Nutrient Management Guide (RB209) available to download as an app for use on mobile digital devices.

The app can be found on Google Play and will coming soon to the App Store. Digital versions are also available to download from AHDB’s website. Among the benefits of using the digital version over printed copies are automatic updates and alerts; the ability to save notes; easier navigation; and integrated multimedia content. Videos, information and recommendations are easy to access in the Guide, which is light to carry and does not need an internet connection to access once downloaded.

The levy board says the guide offers best practice guidance in England, Wales and Northern Ireland on the application of fertilisers and organic materials to crops and grassland. Included in the latest version are new recommendations for cereal crops and phosphate, which are the outcome of 10 years of research work that culminated in 2019.

ADAS, AHDB, Bangor University, Frontier Agriculture, Lancaster University, NIAB TAG, Rothamsted Research, SOYL, SRUC and University of Southampton all worked on the revision of the Nutrient Management Guide.

The Guide is split into seven colour-coded sections, so users can pick the information relevant to them. Sections 1 and 4 have been updated to reflect changes to phosphate management for cereal crops, and section 6 now has more detailed information on courgettes and pumpkins.

Oxfordshire cereals grower James Price, who chairs the RB209 partnership steering group, comments: “Crop nutrition is one of the key elements to optimising production in the field and growers need to use all the tools available to ensure that they manage resources, in terms of soil, applications and plant health.

“RB209 recommendations are based on the most up-to-date science and so offer clear guidance to growers on a whole range of crops from cereals to grass to ornamental bulbs.”
