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.
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.
