# Fertilisers (Sampling and Analysis) Regulations (Northern Ireland) 1996, Paragraph 2: Aggregate sample


The incremental samples shall be thoroughly mixed to form a single aggregate sample. In the case of solid fertilisers the material in the aggregate sample shall be carefully mixed to obtain an homogenised sample. Any lumps inconsistent with the nature of the material shall be broken up (if need be by separating them out and returning them to the aggregate sample).
