Units of Fertiliser Nutrient
Reference to a standard quantity of a named fertiliser nutrient applied per unit area; this is usually given as kg per hectare. For example, 200 units of nitrogen would mean the application of 200kg of nitrogen being applied per hectare, being the equivalent of 20g/N/m². This is not the same as the quantity of fertiliser to be applied because a fertiliser analysis will be less than 100% of nitrogen. For example, applying 200 units of nitrogen using a fertiliser with an analysis of 8% would mean a total fertiliser quantity of 2,500kg to be applied.
