Comparison of the Summit Precision Seeder with the Oyjord Seeder

The Summit Precision Seeder was compared with the Oyjord Seeder at five Forest Service nurseries, using nine conifer species and 26 seedlots. Results varied with seed characteristics, but the Summit did not prove to be a big improvement over the Oyjord. Plots oversown and thinned to target spacings produced less clumping and fewer gaps between seedlings but showed little improvement in seedling size and cull rates over either seeder.
