Foliar chemical concentrations in red alder stands of various ages
Autor: M. A. Radwan, D. S. DeBELL
Publikováno v: Plant and Soil. 77:391-394
Six stands of red alder (Alnus rubra Bong.) were sampled to assess the relationship between stand age and foliar chemical concentrations. The stands ranged in age from 9 to 45 years, and were located near Olympia, Washington, on sites of similar soil

Autor: S. R. Webster, S. P. Gessel, M. A. Radwan, D. S. DeBell
Publikováno v: Canadian Journal of Forest Research. 14:155-162
Effects of different sources of fertilizer N on selected chemical characteristics of soils and foliage, and on growth of western hemlock (Tsugaheterophylla (Raf.) Sarg.) were compared at three different sites in western Washington. Treatments were th

Species Suitability on a Lowland Site Altered by Drainage
Autor: D. S. DeBell, G. R. Askew, J. Stubbs, D. D. Hook, E. G. Owens
Publikováno v: Southern Journal of Applied Forestry. 6:2-9
Surface drainage created adequate conditions for survival and growth of loblolly pine (Pinus taeda L.) on most sites within a wet lowland area. Successful pine establishment occurred on soils having loamy or sandy surface horizons and where original

Responses of loblolly pine (mesophyte) and swamp tupelo (hydrophyte) seedlings to soil flooding and phosphorus
Autor: D. S. DeBell, D. D. Hook, W. H. McKee, J. L. Askew
Publikováno v: Plant and Soil. 71:387-394
In a pot study, flooding reduced growth of loblolly pine (LP) seedlings and caused an imbalance of nutrients, particularly Fe, in the tops. Swamp tupelo (ST) suffered none of these problems. Also under anaerobiosis, LP roots leaked 85 percent of tota

Some Effects of Stand Density on Biomass of Red Alder
Autor: D. S. DeBell, J. H.G. Smith
Publikováno v: Canadian Journal of Forest Research. 4:335-340
Stand density (degree of crowding of trees within stocked areas) was studied in relation to formation and yield of juvenile red alder (Alnusrubra Bong.) stands. Large variations in tree size and biomass of fully-stocked stands were associated with di

Nutrient relations in coppiced black cottonwood and red alder
Autor: D. S. DeBell, M. A. Radwan
Publikováno v: Plant and Soil. 106:171-177
Two-year-old coppice of black cottonwood and red alder, grown in pure culture and in mixture, were compared using terminal twigs and leafless shoots harvested in the winter. Terminal twigs were taken with buds intact; they were about 15 cm long. Leaf
