  2. BIOGEOCHEMICAL CYCLING EXAMPLES 1) Carbon Cycle 2) Nitrogen Cycle 3) Phosphorus Cycle 4) CZ Function and Dynamics

  3. Carbon Cycle

  4. Soil N Cycle

  5. Soil P Cycle

  6. CZ Function and Dynamics • Impacts of hydrology on a given area • Infiltration • Runoff • Weathering of minerals and soils • Soil creation • Nutrient transformation • Human Land Use • Agriculture, Urbanization, and Deforestation are important impacts to these cycles
