Effect of thinning and fertilization on wood properties and intra-ring characteristics in young Douglas-fir

Creator:: Bodner, Josef
Abstract:: The purpose of this study was to determine if thinning, fertilization or a combination of thinning and fertilization had an effect on overall average specific gravity, modulus of elasticity, modulus of rupture, fiber length and intra-ring characteristics. Material for this experiment consisted of 7 trees randomly selected from each of...

Analysis of variability of some forest soils in southwestern Oregon

Creator:: Wicherski, Bruce P.
Abstract:: The variability of selected physical, chemical, and morphological soil properties in two landtype mapping units on'the Rogue River National Forest in southwestern Oregon was studied. The objectives of the study were (i) to quantify soil variability in several soil resource inventory mapping units, (ii) to explore methods of describing soil...

Engineering properties of Southeast Alaskan forest soils

Creator:: Filz, George
Abstract:: The strength of both undisturbed and compacted soils from 10 sites in the slide-prone Tongass National Forest in SE Alaska were studied. Index property tests were also conducted on disturbed samples. The index tests included natural water content, Atterberg Limits, specific gravity of solids, grain size distribution, and moisture-density relationship....

Soil physical properties and available water capacity of southwest Oregon forest soils

Creator:: Flint, Alan L.
Abstract:: Measurements for water retention calculations and physical characterization were made on skeletal and non-skeletal soils in southwest Oregon. A new bulk density sampler was designed for the physical characterization of the steep, skeletal soils commonly encountered in this area. The new sampler and the techniques required for the measurement and...
