Survival was not improved by mechanical site preparation, and seedlings grown on the compacted, low-humus soils associated with piling slash off site did not grow as tall during their first 5 years as seedlings growing on similar sites where slash had been broadcast-burned. Tilling (disking or ripping) did not benefit seedling height growth. West. J. Appl. For. 5(2):49-51, April 1990.",
