|My son Matt collecting soil samples for class. Notice the depth|
of the hole. Notice the tool. When I say rock, I mean rock!!
I'll let the pictures tell the rest of the story, but first here is a little research about our soil:
- We live on the west side of I-35 in southern McLennan County. Our area is known as the "Eddy Series" which consists of shallow to very shallow, well drained, moderately permeable soils. Yes it does!
- Taxonomy class is loamy-skeletal, carbonatic, thermic, shallow. Hmmm...there is a familiar ring to this analysis.
- Our soil ranges from brownish gray to dark grayish brown in color. Check.
- The depth of our soil ranges from 3 to 14 inches thick over chalky limestone. Yes, we found this out when we rented the ditch witch to dig an electrical trench. A job that should have taken 20 to 40 minutes took 3 hours. I wish I was kidding.
- The whole soil contains 35 to 50% chalky limestone fragments by volume. Yes it does!
- The fragments range from very weakly cemented to strongly cemented. Agreed.
- I could go on....but I won't. We have very rocky soil out here!
|Plan B--bring out rock bar. Plan C--"Do you think we can|
rent a jack-hammer?" We would have, but it was Sunday!
While Matt picked and dug at the soil, I stood by with my camera to get a picture of the action! Pictures are a part of the assignment, too. I helped some by removing rock from the soil he would replace in the hole. This took about 2 to 3 hours.
|"Yeah....I think I hit bottom!!!" says Matt.|
Monday morning Matt was delighted to hear that his professor could see "3 horizons" so he had actually dug deep enough. Yes!!!
