Title: Foliar mineral content of forest and nursery-grown Douglas-fir seedlings.

Author: Krueger, Kenneth W.;

Publication Series: Research Paper (RP)

Description: High-vigor seedlings are required for consistently successful reforestation, and mineral nutrition undoubtedly plays a large role in determining seedling vigor. Though no serious mineral deficiencies were known to exist in Northwest forest nurseries, assurance of adequate seedling nutrition would eliminate this factor as a possible cause of plantation failures. Perspective was gained on Douglas-fir nutrition by determining essential element content in foliage of seedlings growing in 10 selected forest areas and 4 nurseries in Oregon and Washington. On the basis of comparative element levels, possible improvements in nursery fertilization are predicted.
