  2. Soil can basically be separated into 5 main parts: • Humus • Clay • Silt • Sand • Gravel

  3. Humus: A dark, moist soil composed of bits of dead, rotting insects, animals, leaves, roots, sticks, and food.  Humus adds nutrients to the soil which plants need to grow and live.

  4. Clay: A soil that holds water.  When wet, clay feels slippery and slimy.  It is made of particles that are smaller than 0.004 millimeters.

  5. Silt: Soil that looks like fine grains or tiny pieces of rock.  Particles classified as silt measure from 0.004 millimeters to 0.006 millimeters.

  6. Sand: Soil that is coarse and drains quickly.  Sand particles measure from about 0.006 millimeters to 2.00 millimeters.

  7. Gravel: Visible rock particles, sometimes referred to as pebbles.

  8. What is a Soil Profile? • A soil profile is a view of a cross section of soil.

  9. Characteristics of the Soil Horizons • 0 Horizon-located on surface, mostly O.M. • A Horizon-Called Topsoil, good amounts of O.M. and minerals. • B Horizon- Known as Subsoil, Less O.M. • C Horizon- Mostly parent material, does little for plant growth.

  10. What is soil texture • It is the relative sizes of the different soil particles.

  11. The major Soil Texture Classes • Sand-largest particle • Silt-medium size particle • Clay-smallest particle

  12. Characteristics of aSandy Soil

  13. Characteristics of a Silty Soil

  14. Characteristics of a Clay Soil

  15. Using the Soil Texture Triangle

  16. What is Soil Structure? • Sand, silt and clay particles combine with one anther to form cluster calledaggregates. • The way in which aggregates or clusters are arranged is referred to as soil structure.
