SAMPLING GUIDELINES

STEP 1

Use a large, clean container in which to collect small portions from multiple locations and depths within the compost pile. Avoid surface layers that may be affected by environmental exposure.

STEP 2

Thoroughly mix the collected material to create a uniform, homogenous sample. Ensure all structural components of the compost are evenly incorporated.

STEP 3

Measure out 250g of the mixed sample.

Place it in a clean, durable plastic bag.

Seal the bag securely to prevent leaks or contamination during transport.

STEP 4

Clearly label the sample with the collection date and a descriptive reference or sample ID.

Cover the label with transparent tape to prevent smudging or damage

STEP 5

Refrigerate the sample immediately after packaging.

Keep it chilled until it is delivered to the laboratory for analysis.
