Forest Service's Wind River Nursery shows that a dramatic buildup of food reserves in late fall and winter is followed by an early spring surge of root growth prior to the start of top growth.

A f:A s ratios reported for various conifers range between m 2 /cm 2 for Juniperus monosperma (Schuler and Smith, ) to m 2 /cm 2 for Abies balsamea (Coyea and Margolis, ) and for Abies lasiocarpa (Kaufmann and Troendle,as adjusted by Waring et al., ). Table I is an updated list, first published in Waring et al., of linear A f:A s ratios reported for a number Cited by: This study showed how selected growth and yield simulations models compare in predicting the results of a set of prescriptions for planted stands of coastal Douglas-fir (Pseudotsuga menziesii var.

menziesii [Mirb.] Franco). Estimates of growth rate, mean diameter, and yield were compared over a rotation for various sites. An economic analysis of the projected estimates was conducted with Author: Nilda Elvira Onate. Re-measurement data over a period of four years from 24 permanent plots were analyzed to determine the effects of three different spacing regimes on growth of uneven-aged interior Douglas-fir (Pseudotsuga menziesii var.

The shape of this growth curve is typical for forests and, indeed, for many other biological organisms; the growth rate increases with time initially (up to about 15 years of age in the figure. In general, though, the monitoring program for most land application systems should include at least some monitoring of groundwater at the perimeter of the site.

Water quality samples should be taken periodically, perhaps as frequently as monthly during the initial period of operation. Later, the frequency can often be reduced to quarterly or less. Commercial Fertilizer Equivalents of the Sludge Application at the Venango County Demonstration Site.

This leads to above normal microfibril angles in the tracheids of the vertical stem, a feature that contributes to the poor wood quality off corewood.

Although compression wood is a naturally occurring phenomenon, it is considered a defect in timber. Clear-cutting and burning of slash of old-growth western hemlock–western red cedar–Douglas-fir stands was followed by relatively small losses of nutrients to streamwaters.
