Soil Science Basics
Learn some basic information about soils, soil chemistry, fertility, and microbiology.
- Dr. Levine, a retired Soil Scientist for soil characterzation for the GLOBE Program talks about the importance of soil, why soil data are important, and how students can take part in soil studies.
- Have you ever wondered just how much soil there is on the Earth to grow plants? Go to "How Much Soil Is There?" to find out.
- A terrific learning activity to introduce soil science and characterization concepts.
- Soil can form pretty slowly. Head over here for some perspective on just how slowly soil forms.
- Here is some information on soil fertility.
- Over time, the four factors below form soil.
- Here are the step-by-step instructions for the GLOBE Soil Characterization protocols. There are images and instructions to download or print out.
