Presentation by high school student Jacqueline Cabuhat

What Is Soil?
“A natural body developed in the unconsolidated mineral and organic
material on the earth’s surface that has properties resulting from the
effects of climate and living matter acting upon parent material, as
conditioned by topography, over a period of time.”
The Power of SOIL
Soil, when not taken care of, can damage our coral reefs.
Studying SOIL
When doing experiments on soil, there are many tests that you can run through to evaluate the soil’s quality.
These include TESTING for:
Nitrogen, Carbon, Calcium, pH value, Organic Material,
And many other tests.
Like animals, soil has been classified into categories known as the 12 Orders of Soil Taxonomy.
The soils of Guam include:
Volcanic soil (primarily South)
Limestone soil (primarily North)
Bottom land/ Strand land soil (primarily South)
There are many topics covered when studying the science of soil:
Soil biology
Soil chemistry
Soil Physics
Soil Genesis and Morphology.
Soil activities and projects conducted at the soil lab and research stations.
