CHLORIDE 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 fi lter 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 fi lter 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.

INTERPRETATION OF CHLORIDE TEST RESULTS

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.

REPLACEABLE CALCIUM 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 fi lter 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 fi lter 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).

6. Use the pipet with the screw cap (0392) to add one drop of Calcium Test Solution
(5108PS). Gently swirl to mix.

7. Hold test tube about one-half inch above the black background in the center of
the Calcium Color Chart (1303). Viewing down through the tube, match sample
turbidity to a turbidity standard. Record as ppm Calcium.
