It's about three month that I have bought this orchard. I have have done Bottle test on my orchard soil. But my test results did not look like what I have seen in internet. So I decided to post my pictures here to get help. I can't figure out percentage of clay/silt/sand from this bottle test. Maybe It's all clay with ab little bit of sand. From the crack is in my soil I expect it's clay. enter image description here enter image description here enter image description here enter image description here enter image description here

The water in the bottle test is almost transparent, so the proportion of clay cannot be significant otherwise the water would remain murky for a long time - unless you have had the bottle standing for a couple of weeks or put in in a centrifuge... It is true that significant sand component would not lead to cracks in dry soil, so this indicates a predominantly silty soil, perhaps with some sand and clay but with these in minor proportions.

  • Thanks for help, These picture have been taken about 24 hours after bottle shake. So if it's mostly silt I am really happy about that, If you have any recommendation for soil improvement I really appreciate that. I want to apply about 10 cm of manure layer on my soil but some people say it will kill your tree. And Also I don't know I can apply that right now or wait for fall.
