not to be confused with dirt which is nothing more than misplaced soil. Soil you find in the garden, dirt you find on the bottom of your shoes and in your house. Elements found in soil include sand and clay and has to do with the size of the soil particles. Other elements such as rocks and organic matter also contribute to the makeup of a soil.

Soil is comprised of small rock and mineral particles (which from the smallest to largest are clay, silt, and sand), organic material, air, moisture, and living organisms. Together, air and water can make up about half the volume of healthy soil. In a soil heavy with clay, water and air will have difficulty penetrating, which leaves soil organisms and plants to suffer. On the other end of the spectrum, the large size of sand particles prevents them from holding water and nutrients in the soil. Silt falls somewhere in between. Loam soil, which is a mixture of all three , is generally accepted as a preferred growing medium.
