Title: Representing Growth Response to Fertilization in the Prognosis Model for Stand Development

Author: Stage, Albert R.; Crookston, Nicholas L.; Shafii, Bahman; Moore, James A.; Olson, John

Date: 1990

Source: Research Note INT-392. Ogden, UT: U.S. Department of Agriculture, Forest Service, Intermountain Research Station; 1990. 6 p.

Publication Series: Research Note (RN)

Description: Capability to represent effects of fertilization has been added to the Prognosis Model for Stand Development. As implemented in version 6, the extension is calibrated only for applications of 200 lb nitrogen applied in the form of urea. Direct and indirect effects are based on growth 10 years after treatment for diameter effects, and 6 years after treatment for height effects. Mortality is not affected in the model. After 10 years, only indirect effects are represented through the normal dynamics of the Prognosis Model. Control of timing is provided through a keyword, the parameters of which are documented in this note.
