Development of tree height and diameter growth equations for mid-Willamette Valley Douglas-fir

Creator:: Ritchie, Martin W.
Abstract:: Equations for predicting height growth, basal area growth and diameter inside bark are presented for Douglas-fir. Basal area growth equations for grand fir are also presented. The growth models were developed for use in an individual tree/distance independent growth simulator. Various model forms and measures of competitive stress were compared...

Strawberries (western Oregon -- west of Cascades) [2000]

Creator:: Hart, John M. (John Mervyn), 1947-, Righetti, Tim, Sheets, W. A. (Willis Arden), and Martin, L. W.
Abstract:: Fertilizer recommendations in this guide are based on the use of well-adapted varieties and disease free plants, selection of suitable soils, disease and insect control, weed control, and proper irrigation. Application of these management practices is essential to realize optimum fertilizer response. Strawberries respond to generous amounts of soil organic...

Equations for predicting height to crown base for fourteen tree species in southwest Oregon

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...
