Significant ideas:
The soil system is a dynamic ecosystem that has inputs, outputs, storages and flows.
The quality of soil influences the primary productivity of an area.
Another time, we will measure:
Moisture content
pH (both acid and carbonate content)
Biomass
Porosity
Earthworms
Soil Systems Diagram
Read Mr G (if necessary) and develop an annotated soil systems diagram.
Your diagram should include:
Inputs
Outputs
Stores
Processes
Transfers
Transformations
Soil Texture Triangle
