I added two full buckets of compost to a hugel bed at Wheaton Labs in the past few days. These were each as full as reasonable, and it seems like no one minded me dealing with both Bucketfuls.

 Bucketful is transferred into the Hole:
 
 
 
 Hole is filled, soil is replaced, and hay mulch is returned. Nobody's the wiser:
 
 
 
 Thanks, volunteer reviewers! :)
