Available in PDF, EPUB and Kindle. Book excerpt: It was decided to examine the effects of soil physical properties on the growth of yellow birch before pursuing the nutrition studies any farther. The purpose was twofold: first to better understand the influence of physical properties themselves; and second, to be able to make some allowance for physical effects when evaluating the effects of chemical and micro-organism factors.

This book was released on 1965 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Work carried out by the Northeastern Forest Experiment Station in West Virginia in the past 12 years provides useful information about the relationships between tree d.b.h. and butt-log grade. The upper logs are not included in the relationships. Being smaller and containing more knots, these upper logs are generally of lower grade than the butt logs. Thus the average grade of all material in the sawlog portion of the tree is generally lower than the average grade of the butt log. In the West Virginia data, species differences in d.b.h.-grade relationship are readily apparent. This inherent tendency for species to have different proportions of the various grades in logs of the same size is a familiar phenomenon to grade-conscious foresters who work with hardwoods. The results in this paper provide a quantitative evaluation of this tendency for six of the local species.S3.
