Employees counting microfauna in soil samples

AFSRC Biologist, Harry W. Godwin, and Biological Science Technician, Melissa M. Johnson, identify and record micro-fauna from two-inch soil core samples extracted with a modified high gradient Berlese funnel system. A two-inch soil core may contain several-hundred micro-fauna specimens. Current data from these samples suggest micro-invertebrates might be responsive indicators for soil management practices.
