Summary
Resting sporangia were collected from dried soil on 37-μm mesh, extracted with chloroform, and deposited on grid, marked membrane filters. The technique gives consistent figures, a rapid estimate of the inoculum potential of a soil, and is suited for analysis of large volumes of soil samples.
