Soil Vocabulary
... Silt: the grain size, or sediment piece, that is smaller than sand but larger than clay. It feels like flour. Soil: a mixture of water, air, sediments (minerals), and humus that covers most of the Earth’s land surface. Top soil: the top layer of soil. Subsoil and parent material lie beneath the top ...

Here is a list of soil tests
... When the soils are wet this causes the particles to move away from each other, so the soil disperses. You have seen this in the aggregate stability test (see 1618C). Dispersion is caused by an interaction between the sodium ions and the particular type of clay. The sodium displaces other useful ion ...
