Ponderosa Pine Response to Nitrogen or Nitrogen Plus Potassium Fertilization - Annual Report Item Info

Title:
Ponderosa Pine Response to Nitrogen or Nitrogen Plus Potassium Fertilization - Annual Report
Creator:
Shaw, T.M.
Date Created (ISO Standard):
1998-08-01
Description:
In 1985, the Intermountain Forest Tree Nutrition Cooperative (IFTNC) established 10 nitrogen (N) fertilization trials in stands dominate by Ponderosa pine. The ponderosa pine trials were located throughout northeastern Oregon and central Washington and were an expansion of IFTNC Douglas-fir N fertilization trials established in the early 1980's. The focus of these fertilization trials was to study nutrition of commercial forests in the Intermountain Northwest, with the majority of the effort on studying the effect of N fertilization on growth and survival. In addition, evidence from IFTNC Douglas-fir trials (Mika and Moore 1990) and other research from the Inland Northwest suggested that elements other than N, particularly potassium (K), may also be limiting. In 1987, IFTNC members established 6 additional ponderosa pine trials in Montana to study the effects of N and K fertilization on tree growth and survival. This report provides 12 year (1985 sites) and 10 year (1987 sites) final response results for the ponderosa pine fertilization sites.
