Materials: -Metal Soil Core -Mallet -Munsell Scale Book -Plastic Bags -Marker/Pen (for labeling) |
-Chemical Test Kit (for testing soil for iron) -Field Notebook -Computer -Look at Troubleshooting page for supply suggestions |
1. Using a
soil core on the same day at the same time, collect 15 cm by 2.5 cm deep
of soil from three different, random locations. |
|
2. While the soil is
still in the soil core, take a pinch of soil and smear it on the color swatches
of the Munsell color scale to match the color
of the soil to a color on the scale. Record the value of the color in the data
table. |
|
3. Remove samples
from soil core and separate them by color into plastic bags labeled with
the site and sample number. |
|
4. On the same day at
the same time, test each sample for ferric iron (Fe+3) in ppm. Record the iron level of each sample in the data table. |
|
5. Repeat steps 1-4 on at least three different days, making sure to collect soil from a different quadrant on each day. | |
