Proceedings of Past Forest Nursery Association Meetings:

A Review of Soil Solar Heating in Western Forest Nurseries
Hildebrand, Diane M.
1989: Bismark, ND
Eleven studies at 10 western forest nurseries are summarized.

soil-borne plant pathogens. Five out of 8 studies reported significant reductions
in weeds. Three out of 5 studies reported an increased growth reponse in a tree
seedling crop. The best results are expected for a tree seedling crop sown soon
after the solar heating treatment.
