The Great Soil Experiment

From the bottom: loamy sand, fine loam, a tiny line of clay and some trash.

Hanni has a clever meme today. She's encouraged us all to take a soil sample, add water and let it settle into layers. You can join the fun Here for Great Soil Experiment.

I've seen the USDA soil report for my county sliced down to about a hundred acres around my garden. As you travel south in that slice, the soils change with the topography:

BlB—Blanton loamy sand, 0 to 5 percent slopes
LmB—Lucy loamy sand, 0 to 5 percent slopes
OcA—Ocilla loamy fine sand, 0 to 2 percent slopes
OeB—Orangeburg loamy sand, 2 to 5 percent slopes
TrB—Troup loamy sand, 0 to 5 percent slopes
The various types of soil have to do with the various layers and their composition.

Right 'round my house is Lucy loamy sand according to the report.
Top 0 to 8 inches; dark grayish brown loamy sand; weak fine granular structure; very friable; strongly acid; abrupt smooth boundary. (4 to 12 inches thick)

I know from digging post holes that clay-sand is 2-3 feet down, depending on where you dig.


If you are really into soils, here's more than you ever wanted to know:

Here's what's blooming in Lucy loamy sand today:

Climbing Peace. I love Peace roses because they're a modern rose as old as I am.

The Peace rose is gorgeous. The first home we ever bought had a peace rose by the front door and I loved that one!

Actually the darkest part just above the sand should be called silt instead of loam. All these terms make my head bizzy.
