I’ve been using this post to determine soil type I have:
The issue is by using web soil survey I get “Sandy loam” with 0.11 available water. However at around 8 inches I have clay layer which would obviously block water runoff. How do I make rachio account it?
Another question is about root depth, I’m in Seattle area, so I chose cold season grass, which set my root depth to 6 inches, however I doubt it is. While moving some sprinklers around I noticed that the maximum depth is around 2-3 inches. Can it be true or am I missing something?
