Abstract

Reports results of fertilizing and thinning pole-size sugar maple and yellow birch crop trees on six different sites. Thinning significantly increased diameter growth, but fertilization did not. Crop trees on moist (moderately well-drained) soils have tended to respond to fertilization. Discusses silvicultural implications.

Keywords
