| 1. Auger to a depth of 1
or 2 cm past the top of the horizon to be
sampled.*
*
Use the depths from the first soil profile
you withdrew with the auger as a guide.

|
| 2. Use the auger to remove
a sample of the horizon. If the horizon
is thinner than the length of the auger
head, partially turn the auger so that the
whole sample will be from one horizon. Do
not turn the auger more than one complete
circle (360°) so that the soil does
not become compacted. |

| 3. Measure the diameter
of the hole the auger made. |
