Cereals: The Arable Event

AHDB Nutrient Management Guide

13-Apr-2017 AHDB

Pick up the AHDB Nutrient Management Guide at Cereals 2017

Visitors to Cereals 2017 will be among the first to get access to the AHDB Nutrient Management Guide (RB209).

Scheduled for release in May, the new publication will be available at the event (which takes place on 14 and 15 June 2017 at Boothby Graffoe, Lincolnshire) from the AHDB Cereals & Oilseeds stand (919).

Nutrient management reviewed

A £98,000 project to review the current Fertiliser Manual RB209 was overseen by the AHDB-led UK Partnership for Crop Nutrient Management and delivered by an ADAS-led consortium of experts from across the UK research community. It was supported by £200,000-worth of in-kind funding by industry.

The 2016 review, which took account of the latest research developments since 2009, was split into six distinct themed work packages: principles of crop nutrient management; organic materials; grass and forage; cereals and oilseeds; potatoes and horticulture.

Farmers, growers, agronomists, breeders, researchers, fertiliser companies and other industry experts were among those consulted on how existing RB209 recommendations could be improved to incorporate the latest scientific advances.

George Lawrie, who chairs the UK Partnership for Crop Nutrient Management steering group, said: “We’ve left no stone unturned during the review, every aspect of nutrient management has been revisited and scrutinised.

“Advances in nutrient management have been incorporated and the new guide will provide evidence-based nutrient management recommendations that growers can trust.”

New format

RB209 offers best practice guidance in England, Wales and Northern Ireland on application of mineral fertilisers, manures and slurries to crops and grassland. The most recent edition was published by Defra in 2010.

Nutrient Management Guide

The updated edition will be split into seven colour-coded sections, so users can cherry-pick relevant information and individual sections can be updated more easily to reflect the latest research.

Yield adjustment

The new guide features numerous changes, including updated recommendations for additional crops and information on the nutrient content of additional organic materials.

Based on the analysis of results from hundreds of trials (conducted between 1981 to 2015), headlining the changes for arable growers will be guidance on how nitrogen applications can be adjusted (up or down) in response to predicted cereal yields.

As the yield adjustment will need to be treated with caution to make sure that it pays, a clear set of guidance will be included in the new publication.

At Cereals 2017, nutrient management experts will be present on stand 919 to discuss the guidance. A nutrient management seminar will also take place at 10:45 on both days.

Key changes for arable crops

  • Updated nitrogen rate tables (winter wheat, winter barley, spring barley, winter oats and triticale)
  • Adjusted nitrogen rates for expected yields (winter wheat, winter barley and spring barley)
  • Changes to nitrogen timings for winter barley and winter oilseed rape
  • Reductions on recommended nitrogen for malting barley
  • Guidance on measuring soil mineral nitrogen
  • Changes to P and K Index build-up options
