Abstract:
Little is known about the chemistry of solutions moving through old-growth coastal temperate coniferous rain forests. The major objective of this study was to examine soil solution chemistry in an old-growth temperate rain forest in the Hoh River valley on the northwest Washington coast 32 km from the Pacific Ocean, and to determine mechanisms involved with changes in solution chemistry. Dominant species were Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco), western hemlock (Tsuga heterophylla [Raf.] Sarg.), western redcedar (Tsuja plicata Donn), and Pacific silver fir (Abies amabilis [Dougl.] Forbes).Soil solution pHs were high as a result of acid neutralization processes, averaging 5.7 in the forest floor and 6.2 at 40-cm depth. Na and Cl dominated soil solutions. Phosphate, NH4, and NO3 concentrations were low in the soil solution, indicating strong retention of N and P in this ecosystem.
Purpose:
The major objective of this study was to examine soil solution chemistry in an old-growth temperate rain forest.

Methodology_Description:
Plots for studying soil solution analyses were established in West Twin Creek watershed in areas representing the two major vegetation zones of the basin; at the base (180 m elevation) and top (800 m elevation) of the watershed. Sampling began October 1986 and was conducted through to October 1991. Soil solutions were collected using tension lysimetry (Cole 1968). Sixty-millimeter diameter, fritted glass Buchner funnels were modified by cutting off the funnel 1 cm above the fritted glass surface and bending the stem at right angles. The modified funnels were placed beneath the forest floor, and at 5 cm and 40 cm below the top of mineral soil. Tension of 0.01 MPa was applied using a 1 m hanging water column. In the lower watershed, three replicate samples for each soil horizon were taken. No lysimeter samples were collected at the upper watershed plot. Soil solutions were collected in 10 L polyethylene bottles, and volumes were recorded in the field. If individual sample volumes were insufficient for analysis, samples were composited by horizon. Soil solutions were sampled monthly, except during dry periods Samples were transported in a cooler to the Analytical Laboratory at the College of Forest Resources, University of Washington, within 48 h of collection and stored at 4° C.

Process_Description:
Specific conductance, pH and alkalinity were determined on non-filtered samples within a few days after arrival at the laboratory. Specific conductance was determined with a YSI Model 31 Conductivity Bridge (Yellow Springs Instrument Co., Yellow Springs, OH) and pH with a Radiometer PHM 85 pH meter (Radiometer, Copenhagen, Denmark). Alkalinity was determined by titration (Rhoades 1982) to an end point of pH 5. After these measurements the water samples were filtered through a Whatman GF/A filter, stored at 4° C and analyzed within a month after arrival at the laboratory. Solutions were analyzed for Ca, Mg, K, and Na using an IL 951 Atomic Absorption Analyzer (Instrumentation Laboratory, Wilmington, MA). Ammonium and NO3 were determined with a Technicon Autoanalyzer II (Technicon, Tarrytown, NY). Sulfate, Cl, and PO4 were determined with a Dionex 2100 Ion Chromatograph (Dionex, Sunnyvale, CA). Dissolved organic carbon (DOC) was determined using persulfate oxidation at 100° C and an OI Model 700 Organic Carbon Analyzer (OI Corporation, College Station, TX).
