Because it is mostly organic matter, it:
Organic horizons are those that contain 17% or more organic carbon; mineral horizons have less than 17% organic carbon. The major symbols used in describing mineral soil layers in Canada are shown in the following tables. The assignment of mineral soil layers to each horizon is done by comparing the properties of the horizons in the field to a ...

- Sandy Soil. Sandy soil is mostly sand particles. It feels gritty to the touch. Because sand particles don’t absorb water but create a lot of space in between for water to move, sandy soil drains quickly and nutrients wash away.
- Silty Soil. Silt is between sand and clay in terms of particle size, and it’s mostly composed of quartz. Silty soil is comprised of at least 80% silt. When dry, silty soil feels like flour.
