Soil is composed of numerous different minerals, and among the most abundant among them is a group known as feldspars, which are minerals containing calcium, sodium, or potassium. Another abundant mineral in soil is quartz.

    • Loam Soil. Loam soil is an even mix of sand, silt, and clay, with the ideal combination being 40% sand, 40% silt, and 20% clay. By mixing them together, each component lends the soil their advantages while lessening the impact of their disadvantages.
    • Clay Soil. Clay soil is soil that is made with 50% or more clay. It’s sticky when wet and rock hard when dry. Just think about it in terms of pottery – you wet the clay to make it malleable, then it dries into a hard substance.
    • 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.
  3. Soil is the loose surface material that covers most land. It consists of inorganic particles and organic matter. Soil provides the structural support for plants used in agriculture and is also their source of water and nutrients. Soils vary greatly in their chemical and physical properties. Processes such as leaching, weathering and microbial ...
