A technique of repeated differential centrifugation for the extraction of microorganisms from soil has been adapted for use with grass silage and compared with the classical stomaching technique. Differential centrifugation proved much more efficient as determined by viable counting procedures. The actual recoveries of cells added to silage were 109 and 9% for the differential centrifugation and stomaching techniques, respectivly
