Am I Sandy Loam, Loam, or Clay Loam?


I live in Katy, TX and the Web Soil Survey for my specific area shows this:

What soil type should I use for landscape that is primarily St. Augustin Grass? I always assumed Clay or Clay Loam but the typical profile in the embedded image shows the below. I assume that the ‘A’ refers to the first 12 inches of soil. That would mean I should set it to Sandy Loam if the root depth of St. Augustine Grass is around 5 inches.

Is that correct?

  • A - 0 to 12 inches: fine sandy loam

All your vegetation except for maybe the BIGGEST trees will be hanging out in above a 24" root zone, so I would go with Sandy Loam.

Perfect. Thank you.
