Soils

1. Depending on the size of the weathered rock it can be

   • Clay
     • Smaller = 0,002
   • Silt
     • Middle = 0,05
   • Sand
     • Big = 2,0

2. Divided in layers

3. Soil orders

   • Entisol
     • No development of the soil horizons
     • Very young
     • Most common on the earth
   • Inceptisol
     • Slightly more horizon development
   • Gelisol
     • High latitude location
     • Permafrost
     • Little horizon development
   • Supdosol
     • Locate in coniferous and boreal forest
     • Acid due to pine needles
     • Low nutrients
   • Afisol
     • Rich in AL y FE
     • Locate on Brodleaf and mediterrean
   • Ultisol
     • Iron makes them red
     • Subtropical and humid location
   • Arisol
     • Dessert soils
   • Mollisol
     • More fertible
     • Grassland soils
   • Oxisol
     • Locate in rains forest
     • Low fertility
     • Very develop horizons
   • Andisol
     • Volcanic soil
     • Rich in nutrients
   • Hitosol
     • Wetland soil
     • Nighly Acid
   • Vertisol
     • High clay content
     • Dry out regulary

4. Order

   • Suborder
     • Great group
       • Suborder
         • Family
           • Series
   • Development of soil

5. Clorpt

   • It´s use to remember the factor that influence soil formation
     • Time
     • Organism
     • Parent Material
     • Relief
     • Climate

6. Soil Facts

   • Is formated by
     • sun
     • rain
     • wind
     • animals
     • plants
