The Nutrient Management Guide (RB209) helps you make the most of organic materials and balance the benefits of fertiliser use against the costs – both economic and environmental. The guide explains the value of nutrients, soil and why good nutrient management is about more than just the fertilisers you buy; it can save you money as well as help protect the environment.

The Nutrient Management Guide is published as seven sections:

You can download the amendment sheet for printed versions from the Tried and Tested Fertiliser page here. 

February 2020 update

The 2020 revision features the first major changes to phosphorus (P) guidance in nearly four decades. 

"The core of the P recommendations for cereals will stay the same, with applications usually made to maintain soils at Index 2. However, grain offtake information has been improved and some maintenance rates will change, due to fine-tuning of standard yields"

January 2019 update

In 2019, the guid was updated to provide further clarity on sulphur management in cereals and oilseeds production. 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’

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