I want to build with cob but where i live our soil is andosol, meaning: is one of the stages of the creation of soil of volcanic origin, which
typically occurs 200 years after a volcanic eruption. I live on a island, in portugal.. do you think my soil with be good for cob? how can i see that?
That jar test shows that your soil is almost all sand (differing sizes but just a very thin layer of silt/clay on top)
You would need to have a way to add clay to that soil profile to be able to make good cob.
