Jan 2, 2019 · How can you tell the difference between mineral and organic soils? Actually, it all comes down to the definition. Ultimately, the thickness of the soil's horizons measured from the surface of the soil defines it.
Apr 19, 2022 · A soilless mix is also called potting soil or potting mix or organic soils. While it is technically a soil because you can grow plants in it, it is mostly organic matter without much (if any) minerals in it. That means it doesn't have much sand, silt or clay in it.
