Abstract:

C55 is a study of thinning and fertilization implemented in a naturally regenerated, high density stand of primarily western redcedar on a low-site quality area on the Olympic Peninsula in western Washington. The fertilization treatments compared effectiveness of urea and ammonium nitrate (2 nitrogen fertilizers) as well as fertilization treatments which included phosphorus, calcium, potassium and sulfur. This data publication contains the response variables, measured between 1980 and 2005, such as tree height and diameter growth, basal area, regeneration, foliar nutrients, stem taper, crown width, branch diameter and regeneration.
