Section 3: Using the recommendation tables

 

 

(See Section 8 for grassland recommendation tables)

To find the correct recommendation for nitrogen, phosphate, potash and magnesium for a particular crop it is important to read the notes that accompany each table.

For nitrogen, Soil Nitrogen Supply (SNS) Index is determined using The Field Assessment Method or The Measurement Method (see Section 1 for details).

For phosphate, potash and magnesium the P, K and Mg Index is based on soil analysis (see Section 1 for details).

More background underlying the principles of nutrient management, including fertiliser applications, for crops is given in Section 1.
