General Information:
Title:Monthly throughfall chemistry, Tomakomai Experimental Forest, May 1990-April 1993
Identifier:JaLTER-toef-04.14.2
Abstract:
Volume-wighted montly mean chemistry of throughfall (n=4) from May 1990 to April 1993 in TOEF, Japan. Note that original data of four replicates at each sampling time are also available in JaLTER metacat. The data are published in Shibata. H., Satoh, F., Tanaka, Y. and Sakuma, T.

Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:
Description:

Throughfall

Collected with rain gutter (0.12 x 3.6 m) under forest canopy

Df site: Deciduous boroad-leaved forest (Natural cool-temperate) (n=4)

Cf site; Coniferous ever-green forest (Plantation of Pinus koraiensis) (n=4)

Four replications in each stand

Mean value are calculated using four replications and volume-wighted mean monthly

Step 2:
Description:

pH

Measured with pH grass electrode

Step 3:
Description:

Ca, Mg, K and Na

Measured with atomic absorption spectrophotometers

Step 4:
Description:

Cl, NO3, PO4 and SO4

Measured with ion chromatography

Step 5:
Description:

Bicarbonate

Measured using titration method (4.3 BX)

Step 6:
Description:

Ammonium

Measured with indophenol blue absorptiometry
