Understanding Fertiliser Analysis: 

• Under the metric system the unit of measurement is a kg
• Recommendations are given in kg/ha
• A fertiliser with the analysis 8:19:10 contains: 8% nitrogen, 19% phosphate, 10% potassium, 5% magnesium.
• So in a 20kg bag: 8% of the 20kg is Nitrogen i.e. 1.25kg N, 19% of the 20kg is Phosphate i.e. 4.75kg P, 10% of the 20kg is Potassium i.e. 2.5kg K, 5% of the 20kg is Magnesium i.e 1.25kg Mg.
