Manual Cyst Extraction
Procedure:
- Obtain a well mixed soil sample.
- Fill a bucket with 2 quarts of water (marked on inside of bucket).
- Pour in the soil, break any clumps with your fingers, and mix the soil suspension well for 15 seconds.
- Pour the soil suspension through a #20 over a #60 sieve.
- Rinse the debris caught on the top sieve with water, and then discard its contents. Carefully wash the cysts and accompanying sediments from the #60 sieve into a clean beaker or directly into a 100 ml plastic grinding tube using as little water as possible.
