Step-by-Step Procedure

1. Prepare the Sample

• Remove the barcode from the sample container and pour the dried soil into the hand sieve.

2. Sieve the Soil

• Gently move the soil through the sieve, use the pestle to break down remaining clumps.
• Ensure the entire sample passes through the sieve.

3. Remove Debris

• Discard of stones, roots and other foreign materials.

4. Clean Equipment

• Clean the sieve and pestle after use. Throw all foreign materials to the bin.
