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.

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.

EWR has an important influence on the amount of nitrate leached and, thus, the nitrogen availability to a crop.

There’s a debate going on about the mandatory use of nitrogen inhibitors for urea fertilisers. Last year, AHDB reviewed the literature to reveal the science behind them and how they could be used to reduce emissions.
