My Department takes samples of fertiliser products placed on the market to verify compliance with Irish legislation under Statutory Instrument No. 248 of 1978. This legislation provides for the labelling of products and sets out the minimum nutrient requirements that must be met (Part 3 of the Schedule of SI 248 of 1978 refers).
The Department has an annual inspection programme, which involves inspections and sampling of fertiliser products. The fertiliser products are tested for a range of parameters specified in the legislation, including Nitrogen, Phosphorus and Potassium. The sample analyses are carried out by the State Laboratory, employing a number of different internationally recognised methods of determination.
There are Standard Operation Procedures for sampling fertilisers, which includes sampling from bagged product, stockpiled product and free-falling finished product. Samples are taken from sample portions ranging from 2 to 40 tonnes, through a process of reduction intended to produce representative final sample portions for testing purposes.
