Soil Chemical, Mr P Reynolds - Coggle Diagram

- - - - Reduced Nutrient Availability
      - Low biological activity
      - Toxic Element Build up -Molybednum
      - Reduced productivity
    - - Reduced Nutrient Availability
      - reduced Nitrogen Fixation
      - Plant Necrosis(death)
      - Reduced productivity
  - - - Test soil for pH
      - Apply lime based on pH Level
      - Drainage
      - Aeration - Subsoil
  - - - Excessive Nutrient Supply
    - - Correct Nutrient Level
    - - Average fertility, requires nutrients
    - - Low Fertility, low Nutrient
- - - - Positive Charge
  - - - Replaces Hydrogen ions with Calcium Ions
      - Allows soils release nutrient ions to plant roots to uptake
      - Calcium ions very attractive to soil
      - Removes hydrogen from soil which increases pH
