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

Four replications in each stand

Sample ID 2, 3, 4 and 5 were observed in deciduous broad-leaved forest (Df-site)

Sample ID 12, 13, 14 and 15 were pbserved in coniferous evergreen forest (Cf-site)

Step 2:
Description:

Stemflow

Collected using PVC tube rolled obliquely around trunk.

Sample ID 6 was observed at Quercus crispula.

Sample ID 16 was observed at Pinus koraiensis

Step 3:
Description:

pH

Measured with pH grass electrode

Step 4:
Description:

EC

Measured with EC electrode

Step 5:
Description:

Ca, Mg, K and Na

Measured with atomic absorption spectrophotometers

Step 6:
Description:

Cl, NO3, PO4 and SO4

Measured with ion chromatography

Step 7:
Description:

Bicarbonate

Measured using titration method (4.3 BX)

Step 8:
Description:

Ammonium

Measured with indophenol blue absorptiometry
