Growth Rates after Fertilizing Lodgepole Pine
Heavy application rates of nitrogen (N), phosphorus (P), and sulfur (S) to thinned lodgepole pine (Pinus contorta) produced responses in volume increment directly related to increased tree nutrition that lasted no more than 8 years. An indirect response in volume increment, resulting from increased levels of stocking after fertilization, continued for a longer period. Resulting increases in yields probably cannot economically justify operational fertilizing in similar stands. West. J. Appl. For. 4(1):18-20, January 1989.

More about this publication?
- Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Western Journal of Applied Forestry covers the western United States, including Alaska, and western Canada; WJAF will also consider manuscripts reporting research in northern Mexico that has potential application in the southwestern United States.
