Recommendations for Calibrating Mechanical Seeders

Because of its effectiveness and low cost, aerial seedling (following mechanical scarification) is commonly employed as a method of regenerating jack pine (Pinus banksiana Lamb.). In Ontario, the Brohm seeder (2) is the standard seeding device, and it is calibrated by using a calculation based on the number of seeds per gram to obtain a desired number sown per hectare. Observed differences between actual sowing rate and the rate set on the seeder (Riley, L.F. 1977. Canadian Forestry Service, Sault Ste. Marie, Ontario, pers. commun.) prompted a search for sources of the discrepancy. One such source is seed moisture content.
