MODEL EP • CODE 1055

The Model EP Soil Sampling Tube is a hollow cylinder of galvanized steel
with a handle at one end and a saw-toothed cutting edge at the other.
One side of the cylinder is cut away to permit inspection of soil core
stratification. The sampler is twelve inches in length and removes a soil
core one inch in diameter. The cutaway “viewing window” begins one
inch above the cutting edge and is 9m inches long.

PRO CE DURE

1. Holding the tube in a vertical position, force it into the soil
approximately six to nine inches. Leave about one inch of the
cutaway portion of the tube showing above the surface of the soil.
Deeper penetration will compress the soil in the tube, making it
difficult to remove.

2. Twist the tube back and forth to sever the core.

3. Continuing to twist the tube back and forth with a rapid motion, lean

the tube toward you with the cutaway portion facing up and slowly
withdraw the tube from the soil. The twisting motion will insure that
the tube is withdrawn without breaking soil or turf, resulting in a
perfect soil sample. The wetter the soil, the more carefully these
instructions must be followed.

4. Remove the soil sample through the cutaway portion of the tube.
When soil tests are to be performed on sample taken from a particular
depth (e.g., six to eight inches), simply measure downward from the
top of the soil core to locate soil from the desired depth. Use a clean
utensil to dislodge soil remaining in the tip of the sampler.

A detailed discussion of the proper technique for collection and
preparation of soil samples may be found in any one of the publications
available from LaMotte Company: The Garden Guide Manual (36250), A
Study of Soil Science (1530), or The LaMotte Soil Handbook (1504). An
abbreviated discussion of soil sample collection and preparation is printed
on each LaMotte Soil Sample Bag (Code 0615). Achieving optimum
results with LaMotte soil test equipment requires careful attention to the
sampling process.
