Effectiveness of an Underground Storage Unit for Loblolly Pine Seedlings

An underground seedling storage unit was constructed on the Cumberland State Forest in the summer of 1965._- A study was made in 1966 and 1967 to evaluate the effectiveness of this unit compared to an unheated open shed for storing loblolly pine seedlings. The underground storage unit (referred to hereafter,, as the "unit") was constructed of cinder blocks in an excavation in the side of an embankment (fig. 1). The floor and roof were poured concrete. Soil was piled against the sides of the unit, and also over the roof to a depth of 1'/2 feet. A door in the front end opened to the north and there were vents in the door, and in each end of the roof. The dimensions of the unit were: length-20 feet, width-12 feet, and height8 feet. The capacity was 300,000 to 400,000 loblolly pine seedlings. The open shed storage facility" (referred to hereafter as the "shed")- was an equipment shed enclosed on three sides and open to the north. It was located about 200 yards from the underground storage unit.
