Actually, I've found "well cured compost" is pretty damp-off suppressive
in greenhouse conditions, also.  But I'm talking about well-cured compost
+ sterile potting mix + perlite or sand as a seedling germination medium
for greenhouse use, rather than a couple of shovelfuls of garden soil
amended directly with compost and sand.

For more information, see Ringer, CE et al 1997.  Suppression of
seedling damping-off disease in potting mix containing animal
manure composts.  Compost Science and utilization 5(2):6-14
