- Description:
- Foliar diagnostic tools have been used with varying success to identify limiting nutrients in Douglas-fir (Pseudotsuga menziesii [Mirab.] Franco var. glauca [Beissn.] Franco). The mechanisms of sulfur and nitrogen metabolism in plants enable the measurement of nutrient fractions that may yield more informative results. Measurements of sulfate-sulfur in conifer foliage have shown potential as a diagnostic tool for predicting tree response to nitrogen fertilization. Using archived samples and data from previously established fertilizer trials in northern Idaho, we tested the relationship between foliar sulfate-sulfur concentrations in unfertilized trees and 2-year growth response to nitrogen fertilization in Rocky Mountain Douglas-fir (P. menziesii [Mirab.] Franco var. glauca [Beissn.] Franco). Sulfate-sulfur concentrations explained 42% of the variability in growth response, compared with 17% for the total nitrogen to sulfur ratio. Sulfate-sulfur concentrations were variable within sites, presenting a challenge to the feasibility of sampling. Our results suggest that further controlled research would aid in development of sulfate-sulfur as a foliar diagnostic tool.
