1. Sampling procedure with soil core sampler

2. The vertical soil core sampler is inserted into the soil using a heavy hammer When the soil is hard or dry, a larger hammer is required to insert the soil sampler

3. In soft sandy soils, a smaller hammer is needed

4. The handles are used to maintain vertical penetration of the sampler without risking injuries to the assistant

5. The soil sampler is completely inserted into the ground in about 1-2 minutes

6. The U-shape jaw accessory is attached to the soil sampler tube inside the ground. A good fit helps with extraction

7. Using the car jack, the soil sampler is easily retrieved in about 2 minutes

8. Strong workers are not required The work effort of the car jack is equivalent to lifting a passenger car for replacing a tire

9. A soil core is extracted from the tube by the compactor (or a spatula, not shown) The soil core is placed in plastic bags that are delivered for laboratory analysis

10. Example of an extracted soil core
