|Immediately after shaking|
I went for this basic test - Mason jar with a lid, an old measuring cup and some water. That is science I can cope with.
|After it has settled.|
Put the top on tight and shake well.
Allow it to settle. (I let it sit for about a half hour)
Shake it again.
Put the jar in a place where it will remain still for 5 to 7 days. You will see the soil settle into layers and the water will be as clear as it can be in a jar full of dirt.
The bottom layer should be small rocks
The next layer up should be fine sand
The next layer up should be silt
The next layer up should be clay
Then the little root pieces and things that float, and then the rest should be water.
What you want to see are layers that are 2/5ths sand, 2/5ths silt and the rest is clay. This means you have loam which is the best soil. Lets just say that I don't have loam.
If over half of your sediment is silt with a little clay then you have heavy silt soil.
If more than 1/4 of your sediment is clay and you have lots of silt then your soil is considered clay.
After turning the jar around and observing the sediment, I think my dirt falls into the heavy silt category. Observations and conclusions - sounds like I just did a little science.
