Soil Science

The study of soil can provide fertile ground (pun intended) for a lot of good science.

While it is often overlooked and thought of as mere ‘dirt’, soil is in fact a complex mixture of organic matter, minerals, gases, liquids, and organisms that together provide an environment that can support life. It has several critical functions:

  • a medium for plant growth
  • a means of water storage, supply and purification
  • a modifier of Earth’s atmosphere
  • a habitat for organisms

The document below describes a few simple experiments to investigate some of the physical and chemical properties of soil:

  • Temperature
  • pH
  • Moisture content
  • Density
  • Permeability
  • Porosity
  • Particle size and
  • Organic content
