Macrobotanical Analysis - Clarissa Cagnato
This sieve will catch the lighter particles, while the heavier plant remains will stay in the bucket. Manual water flotation is usually easier to set up, especially in the field, and inexpensive. However, it can be time consuming and labor intensive, and usually does not make sense for processing very large samples of soil.Read More
