| 1. Use the clean pipette
to transfer the clear solution above
the soil to a clean test tube until
it is filled to the shoulder. (If more
solution is needed, repeat Part 1). |
|
|
| 2. Add one Potassium
Soil Tablet to the tube. Be sure that
all the pieces of the tablet are added
to the test tube. Cap and mix until
the tablet disintegrates. |
|
|
| 3. Hold the tube over
the black boxes in the left column of
the K portion of the color chart. Look
through the "cloudiness" of
the solution in the test tube and compare
it to the shaded boxes in the right
column. Record your results (High, Medium,
Low, or None) on the Soil Fertility
Data Work Sheet. |
|
|
| 4. Discard the solution
and wash the tube and the pipette with
distilled water. |
| 5. Repeat this procedure
with the liquid from each of the soil
samples. Be sure to rinse the pipette
and tube with distilled water after
they are used. |
