Why use the Nutrient Management Guide (RB209)?
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.
In this section:
This section provides guidance for vegetables and bulbs, and it is recommended that it is read in conjunction with Sections 1 and 2.
For each crop, recommendations for nitrogen (N), phosphate (P2 O5 ) and potash (K2 O) are given in kilograms per hectare (kg/ha). Magnesium (MgO), sulphur (as SO3 ) and sodium (Na2 O) recommendations, also in kg/ha, are given where these nutrients are needed. Recommendations are given for the rate and timing of nutrient application. These are based on the nutrient requirements of the crop being grown, while making allowance for the nutrients supplied by the soil.
