Book excerpt: Excerpt from Response of Douglas-Fir Seedlings to Nitrogen, Sulfur, and Phosphorus Fertilizers This study, therefore, was designed to study effects of N, S, and P additions on growth and nutrient content of Douglas - fir seedlings grown in two forest soils in a lathhouse. We are aware of the limitations of pot tests in providing prescriptions that can be directly applied to field situations. However, the very limited information about Douglas - fir nutrition now available and the high cost of establishing field tests strongly justify preliminary experimentation with seedlings.

This book was released on 1981 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen and phosphorus were applied to young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees to determine their effects on deer browsing and tree growth. Nitrogen (N) proauced measurable responses in browsing of terminal shoots and growth of trees the first year, but effects were mostly negligible 2 years after treatments. No responses to phosphorus (P) were detected. Nitrogen and N+P treatments increased the concentration of N in tree foliage the first year, but amount of moisture, ash, calcium, and P were not affected after 2 years.

Attributes of seedling quality are categorized as either to cutting buds. to scraping bark to detect dead cambium. performance attributes (RGP. frost hardiness. stress resistance) One nursery reported using frost hardiness as an indicator of or material attributes (bud dormancy. water relations. nutrition. when to begin fall lifting. but none reported using it as an morphology). Performance attributes are assessed by placing indicator of seedling quality before shipping stock to customers. samples of seedlings into specified controlled environments and evaluating their responses. Although some effective short 23.4.3 Stress resistance cut procedures are being developed. performance tests tend Only three nurseries measure stress resistance. They use to be time consuming; however, they produce results on whole the services of Oregon State University and the test methods plant responses which are often closely correlated with field described in 23.2.3. One nursery reported that results of stress performance. Material attributes. on the other hand. reflect tests did not agree well with results of RGP tests and that RGP only individual aspects of seedling makeup and are often correlated better with seedling survival in the field. Most stress poorly correlated with performance. tests are conducted for reforestation personnel rather than for Bud dormancy status seems to be correlated. at least nurseries.
