  2. Parent Material - 100 • Parent material, climate, organisms, topography and time. Factors of Soil Formation

  3. Parent Material- 200 • Mixtures of minerals Rocks

  4. Parent Material - 300 • Igneous or sedimentary transformed by high heat and/or pressure Metamorphic

  5. Parent Material- 400 • Poorly sorted fragments on steep slopes or at foot of slopes, carried by gravity Colluvium

  6. Parent Material - 500 • Wind-carried silt Loess

  7. Taxonomy - 100 • The great group Haplaquolls belongs to this soil order. Mollisols!!! And you Better know this one

  8. Taxonomy - 200 • The great group Hapludoll belongs to this soil order, soil moisture regime, and will support this major crop. Mollisols, udic, corn

  9. Taxonomy - 300 • When comparing these two soil subgroups, which one is the “wettest?” • Typic Haplaquolls • Aquic Hapludolls Typic Haplaquolls

  10. Taxonomy- 400 • Place the following three soils in correct order from high to low elevation in a soil toposequence. • Clarion—Typic Hapludolls • Webster—Typic Haplaquolls • Nicollet—Aquic Hapludolls Clarion, Nicollet, Webster

  11. Taxonomy - 500 • Place the following three soils in correct order from high to low elevation in a soil toposequence. • Clarion—Typic Hapludolls • Markey—Typic Borosaprists • Webster—Typic Haplaquolls • Nicollet—Aquic Hapludolls Clarion, Nicollet, Webster, Markey

  12. Morphology - 100 • Five common soil structure descriptors Granular, subangular blocky, angular blocky, massive, columnar, prismatic, single grain

  13. Morphology - 200 • Brightness or purity of the color. • Amount of grey added. • 1 = high grey (low purity) • 8 = low grey (high purity) • Chroma of 2 or less = gleyed conditions, poor drainage. Chroma

  14. Morphology - 300 • Spectral color of rainbow Hue

  15. Morphology - 400 • A soil color of 10YR 3/2 refers to what three attributes (must be in correct order) Hue, value, chroma

  16. Morphology - 500 • These features are attributed to strong soil structure aeration, lower bulk density, porosity, drainage, increased rooting depth, etc.

  17. Etc. - 100 • Unconsolidated mineral and organic material that serves as a natural medium for the growth of plants... Soil

  18. Etc. - 200 • Nitrogen (NO3-), NH4+) • Phosphorus (H2PO4-, HPO42-) • Potassium (K+) • Calcium (Ca2+) • Magnesium (Mg2+) • Sulfur (SO42-) Plant nutrients from soil

  19. Etc. - 300 • C (CO2) • H (H2O) • O (O2, H2O) Plant Nutrients from air

  20. A E B C R Etc. - 400 • Unconsolidated down to the bedrock is referred to as the Regolith

  21. A E B C R Etc.- 500 • The is the part of the soil profile that has weathered from the parent material, generally the A and B horizons Solum

  22. What soil order? - 100 Mollisols

  23. What Soil Order? - 200 Alfisols

  24. What Soil Order? - 300 Spodosols

  25. What Soil Order? - 400 Ultisols

  26. What Soil Order? - 500 Histosols
