Book Description
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.

Effects of Nitrogen and Phosphorus Fertilizers on Deer Browsing and Growth of Young Douglas-fir
Author: Glenn LeRoy Crouch
Publisher:
ISBN:
Category : Browse (Animal food)
Languages : en
Pages : 16
Book Description
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.
