To fully understand why soil is important for gardening, you must first ask: What is soil?
Soil is a mixture of minerals, nutrients, and organic matter with a parent material such as rock erosion or sediment. Fertile soil has everything a plant needs to survive.
There are different textures of soil, including sand, silt, and clay. The combination of these three-particle textures is what creates all the different types of soil. For example, loam is a common gardening soil, and it has about the same amount of sand and silt, with less than 27% clay. On the other hand, desert soil is composed of 90-95% sand.
The phase of the soil formation will effect it’s content of sand, clay and silt.
