Abstract:
The evidence from the data to date indicates that when temperature and moisture conditions are regulated, the aspen soil gives 100% possible germination, the granite soil 65%, the quartzite soil 47%, and the nursery soil 29%. The losses due to wilt or damping off amount to as much as 10% and to pests to as much as 5%. Differences in soil account for as much as 50% reduction in germination. Steam sterilizing encourages loss from mold and wilt rather than decreasing them.
