  3. 8. "O" Horizon is referred to as this. Made up of partially decayed plant and animal debris
  4. 9. materials may be altered in the soil
  5. 11. Bad for porosity ties up water so plants can't use it
  6. 13. refers to the slope characteristics of a soil
  7. 14. Clay, chemicals, & organic matter is very leached in this layer. Usually occurs in sandy forest soils
  8. 15. Adds porosity and reduces water holding capacity
  9. 16. "B" Horizon "Zone of accumulation
  10. 17. materials such as fallen leaves, wind-blown dust, or chemicals from air pollution that may be added to the soil
Down
  1. 2. materials may be moved within to soil
  2. 3. "C" Horizon is influenced less by the soil forming processes
  3. 4. soil that has been moved by natural processes
  4. 5. A soil that is a mixture of sand, silt, and clay
  5. 6. "A" Horizon is the surface layer where organic matter accumulates
  6. 10. Moderately good for porosity helps water holding capacity
  7. 12. "R/D" Horizon is rocks such as limestone, sandstone, or granite.
