Title:

Soil Water (Lysimeter) Chemistry for Mature Balsam Poplar and White Spruce for BCEF

Contacts:

Brenner, Richard

Abstract:

This dataset includes soil water samples (lysimeter samples) collected from mature balsam poplar (BP1, BP2 and BP3) and white spruce (FP4A, FP4B, FP4C) stands during 2000 and 2001. Five Lysimeter were installed at 12 cm and four at the 40 cm in each stand type. Water from the Tanana River and small, non-silt, streams on the eastern portion of the floodplain were collected during many sampling periods.

Site References:

BP1 -- True balsam poplar stand on the Tanana River floodplain within Bonanza Creek Experimental Forest, Fairbanks, Alaska, USA. Vegetation structure for these sites includes a closed canopy of mature (>100 yrs old) balsam poplar with a dense thin-leaf alder (Alnus tenuifolia) understory. Basal area for stems larger than 5 cm averages 36.7 m2 ha-1 and 1.8 m2 ha-1 for balsam poplar and alder, respectively, with densities for poplar ranging from 567 to 922 stems ha-1 among the three stands. Total litterfall averaged 279 g m-2 y-1 across the three stands during the 1998–99 growing season. Rose (Rosa acicularis) and high-bush cranberry (Viburnum edule) are prominent within the shrub layer, filling understory canopy gaps previously occupied by decadent alder shrubs. Average daily soil temperatures measured at a depth of 7 cm during the 1998 growing season ranged from a minimum of 3.8°C in May to a maximum of 11.4°C in late July. The soil, classified as typic cryofluvent, consists of an alluvium of fine to medium sand grains overlain by a well-developed organic profile extending to more than 8 cm in some places. Soil C:N ratios average 19.0 for the organic layer and 16.0 for the mineral soil.
