Welcome to the Nutrient Management for the Enhanced Productivity Douglas-fir Stands web site!

This website is an on-line "toolbox" of productivity management tools for characterizing a given site,  estimating a sustainable target productivity and using  several nutrient management models.  Enter the website for:
 

FERTILIZATION RESEARCH RESULTS

  • Tree growth response
  • Environmental effects of N fertilization
  • Enhanced carbon sequestration


NUTRIENT MANAGEMENT TOOLS:

  • Diagnosis: Determine the nutrient status of the site from simple foliar nutrient analyses
  • Site Characterization Maps: Estimate productivity targets
  • RemSS:  Simulate nutrient requirements for target tree growth
  • NuCSS: Forecast soil nutrient supply based on target tree growth and management options
Plus links to many useful forestry sites...
