Description:
The spatial distribution of foliar nutrient concentrations in Douglas-fir and grand fir species was investigated in a study conducted in northern Idaho. Mensurational data were collected from 55 Douglas-fir and 69 grand fir individual trees from 14 one-half acre plots. Foliage samples from the third whorl ofeach tree were taken, and tree positions were mapped using a Global Positional System (GPS). A stochastic modeling method, the sequential conditional Gaussian simulation, was used to study tree volume and foliar nutrient flow dynamics. Spatial variations were analyzed between individual tree measurements and nitrogen, potassium and boron concentrations under different fertilization treatments. The study showed that there are species differences in the distribution of foliage nutrient concentrations and tree biomass. Potassium and boron concentrations were lower in plots treated with high nitrogen rates. Boron concentration values were higher on the untreated plot.
