The Nutrient Management Guide (RB209) provides guidelines for crop nutrient requirements and the nutrient content of organic materials. It is published as seven sections:
Section 1 Principles of nutrient management and fertiliser use
Section 2 Organic materials
Section 3 Grass and forage crops
Section 4 Arable crops
Section 5 Potatoes
Section 6 Vegetables and bulbs
Section 7 Fruit, vines and hops
Profitable farming requires continued development and use of a wide range of skills. Good nutrient management is an important aspect of this and can contribute to business efficiency and reduce environmental impacts.
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. It 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.
RB209: Nutrient Management is a FREE app, which allows you to navigate all seven sections of the Nutrient Management Guide (RB209). It is available in the App Store for Apple devices and on google play for android devices.
The Nutrient Management Guide (RB209) will be updated regularly and AHDB can send you updates when they are published. Please complete this form if you would like to be kept up to date.

If you?re following the Field Assessment Method in RB209 to assess soil nitrogen supply (SNS) and need to determine the Excess Winter Rainfall (EWR) for your area, visit our EWR maps page.
Excess winter rainfall (EWR) is the amount of rainfall that drains through the soil, leaching nitrates present in the soil after harvest of last year?s crop. Compared to total rainfall, excess winter rainfall is a better indicator of nitrate losses during winter. This could help in a better assessment of SNS when planning for nitrogen applications during spring.
