The Demineralizer Bottle will be the source of all the deionized water in
these tests. Read the Demineralizer Bottle Instructions before
proceeding.

CHLO RIDE IN SOIL TEST

1. Fill a 1-8 mL test tube (0755) to line 5 with deionized water from
the Demineralizer Bottle (1151).

2. Use the 0.5 g spoon (0698) to add four level measures of soil. Cap
and shake for one minute.

3. Fold a piece of filter paper (0465) in half. Fold in half again.
Holding pointed end down, squeeze corners together to form a
cone. Insert into funnel (0459).

4. Filter soil suspension through filter paper. The clear soil extract is
used for the test.

5. Use a transfer pipet (0364) to add 5 drops of the extract to a test
tube (0242).

6. Use the dropping pipet (0352) to add one drop of *Chloride Test
Solution (5111). Gently swirl to mix.

7. Hold test tube about one-half inch above the black background in
the center of the Chloride Color Chart (1304). Viewing down
through the tube, match sample turbidity to a turbidity standard.
Record as ppm Chloride.

IN TER PRE TA TION OF CHLO RIDE TEST RE SULTS

Chlorides are present in small amounts in practically all soils. Large
amounts of chlorides in soil may be toxic to growing plants, and may
produce stunted plants.

RE PLACE ABLE CAL CIUM IN SOIL TEST

1. Fill a 1-8 mL test tube (0755) to line 7 with *Universal Extracting
Solution (5173PS).

2. Use the 0.5 g spoon (0698) to add four level measures of soil. Cap
and shake for one minute.

NOTE: When adding samples with high concentrations of
carbonates to *Universal Extracting Solution (5173PS), swirl tube
to mix for 30 seconds before capping to allow gases to escape.

3. Fold a piece of filter paper (0465) in half. Fold in half again.
Holding pointed end down, squeeze corners together to form a
cone. Insert into funnel (0459).

4. Filter soil suspension through filter paper. The clear soil extract is
used for the test.

5. Use a transfer pipet (0364) to add 5 drops of the extract to a
turbidity test tube (0242).
