What Soil Type in Rachio is Sharpsburg Silt Loam


#1

So I did a survey on my land area and it comes up that it’s Sharpsburg Silt Loam. I’m trying to determine which soil type to pick in Rachio that best describes this. My lawn was sodded in the summer of 2015 and I core aerated it in the fall of 2016.

This is what I was able to find about my soil, but I am not sure if I should pick Loam, Clay Loam, or Silty Clay.

[10 to 25 centimeters (4 to 10 inches) thick]

C–117 to 152 centimeters (46 to 60 inches); mottled grayish brown (2.5Y 5/2), yellowish brown (10YR 5/4), and brown (7.5YR 4/4) silty clay loam; massive; firm; very few fine roots; common fine iron and manganese oxide concretions; slightly acid.

I went ahead and decided on Clay Loam for now. USDA has the soil with an AWS score of 0.23.

Hi @BuddyL33!

I think that Clay Loam sounds like your best fit. Let me know if I can answer any other questions!
