| 1.
Identify a location where you either know there is high
decomposition or suspect there is high decomposition |
|
2.
Pick and mark plots 5 meters apart moving away from the area of
high decomposition moving towards an area of low decomposition.
Mark each plot with a flag labeled 1, 2, 3, 4, or 5 |
|
3.
Record observations of weather in the past 24 hours in
respective area |
| 4.
Complete steps 5-8 in the same hour on the same day. |
5. Using a soil
core extractor, extract 3 samples 15 cm deep with a diameter of
2 cm from plot, 1 in the same elevation 10 cm away from each
other
|
| 6. Put each
extracted soil sample in plastic bags labeled 1A, 1B, 1C and
also label the date |
|
7.
Make sure to rinse soil core extractor between extractions to
prevent contamination |
|
8.
Repeat steps 5-8 for plots 2-5 |
9. Bring soil to
lab station and prepare for the lab by putting on safety goggles
and gloves: make sure hair is tied up and wear closed toed shoes
 
 |
| 10. Using a
chemical test kit and Figure 1, complete Phosphorus and Humus
Test |
|
11.
Use Figure 1 to convert Phosphorus data into unit PPM |
|
12.
Record data in a data table |
|
13.
Complete steps 4-12 on different days |
