This article briefly looks at the type of information that is typically included on a bag of fertiliser.
The example bag of fertiliser includes the following details:
- "Turf Food" - This is typically the product name, which may be a associated with a particular company.
- Spring and Summer - Most commercial fertilisers are given as either suitable for use during 'Spring and Summer', or 'Autumn and Winter'.
- for Fine Turf - The general area of application is typically identified: This may be fine turf, sportsfield, amenity turf or similar.
- 15 : 5 :10 - This is the nutrient analysis of the fertiliser and indicates the percentage amount of Nitrogen, Phosphate and Potash within the bag. The total of these three major nutrients in this example is 30%. The remainder of the bag will be made up of other chemicals, for example, sulphur, oxygen, calcium, hydrogen etc. to which the main nutrients may be chemically bound, as well as inert filler material.
- 25 kg - Most fertiliser bags come in a standard size of 20 to 25 kg, however, other sizes are possible.
With the bag having a percentage analysis of 15 : 5 : 10, the following amounts of each nutrient are contained within the example 25 kg bag:
- Nitrogen = 3.75 kg;
- Phosphate = 1.25 kg;
- Potash = 2.5 kg.
