RB209 Section 4 Arable crops
In this section you will find information on how to determine the nutrient requirements of cereals, oilseeds, peas and beans, sugar beet and biomass crops.
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 App
All seven sections of the Nutrient Management Guide (RB209) can now be downloaded as an app.
Available in print
Note: The print edition of Section 4 contains an error. Phosphate and potash recommendations (Tables 4.12 and 4.13) are in kg/ha, not t/ha.
Excess winter rainfall (EWR) tool
EWR has an important influence on the amount of nitrate leached and, thus, the nitrogen availability to a crop.
