Soil Sifting

This is a recording of individual soil samples being sifted and grinded after having been dried in a Burlese funnel system. This sound was recorded in the Plyler Hall Ecology Laboratory at Furman University while conducting a biological study on the effects of soil quality on the biodiversity of microinvertebrates. The intention behind sifting and grinding soil is to reach a consistency at which a carbon and nitrogen composition analysis can be performed.
