  20. III. Major Soil Types

  21. III. Major Soil Types A. Method: non genetic, based solely on physical properties

  22. III. Major Soil Types A. Method: non genetic, based solely on physical properties

  23. III. Major Soil Types A. Method: non genetic, based solely on physical propertiesB. Soil Types (Orders)there are 12 total…..we will examine some of these.

  24. Inceptisols Mollisols Ultisols Oxisols Aridisols Vertisols Soil Orders

  25. Inceptisol Found on steep hillslopes and floodplains

  26. Ultisols Common in forested areas

  27. Oxisol Common in the tropics

  28. Mollisol Common in prairie environments

  29. Vertisol

  30. Aridisols

  31. IV. Synthesis of Climate, Time, and Parent Material

  32. V. Soil FertilityA. Fertilizers 5 – 10 - 5

  33. V. Soil FertilityA. Fertilizers 5 – 10 – 5N P K

  34. V. Soil FertilityA. FertilizersNitrogen

  35. V. Soil FertilityA. FertilizersNitrogen * darker, stronger leaves

  36. V. Soil FertilityA. FertilizersNitrogen * darker, stronger leaves * helps with uptake of other nutrients

  37. V. Soil FertilityA. FertilizersPhosphorous

  38. V. Soil FertilityA. FertilizersPhosphorous * strengthens stems and roots

  39. V. Soil FertilityA. FertilizersPhosphorous * strengthens stems and roots * enhances flowering, and seed production

  40. V. Soil FertilityA. FertilizersPhosphorous * strengthens stems and roots * enhances flowering, and seed production * increases plant’s resistance to certain diseases
