• Soil is the loose material that covers the land
  areas of the earth may extend downward for
  hundreds of feet before reaching bedrock. It can
  be penetrated by living organisms.

Mr. Butlers Interview

• 1. What is soil tested for?
• Testing the soil is for pH, and is also the most
  important thing you can test. It is tested for
  nitrogen, nitrates, ( fertilizer ) and
  phosphorus.

4

• 2. Why is soil testing important?
• For monitoring soil, so it remains balanced, and
  to determine if conditions are healthy for the
  plants.

5

• 3. What is soil composed as?
• Broken down rock, decomposed plant and animal
  matter, minerals.

6

• 4. Why did you get involved in soil testing?
• Because everyone else chose the cool stuff,
  somebody had to do it.

7

• 5. How many students do you take?
• I invite five, but usually two or so actually
  show up.

8

• 6. Do you like the students and other teachers
  you work with?
• Most of the students are very cooperative.

Water and Soil

• The rocks and minerals of the land mass determine
  that nature of the soil. If no water is added,
  the system does not change. However, addition of
  water causes changes that form the soil profile.

Maria Saunders Interview

• 1. Why did you go to Rose bay?
• Because I had to go with my group, and we had to
  set up for our day.

11

• 2. Did you like soil testing?
• It was interesting. Ive never done anything
  like that before.

12

• 3. What did you learn?
• I learned how to test soils pH levels.

13

• 4. Did you have fun?
• YES! Even though it was pretty dirty, I still
  had a great time!

14

• 5. Would you go again?
• Absolutely, especially if were pepper
  busting!!!!!!!!!!

15

• 6. Why did you participate in the Rose Bay
  Project?
• Because my group was going, and I wanted to find
  out what soil testing was like.

Types of Soil

• Tundra soil- permanently frozen substrata called
  permafrost.
• Desert soil- these soils have calcium
  carbonate(lime) and other salts
• Chestnut, Chernozem, and Prairie soils- these
  soils have thick organic-rich surface, filled
  with calcium and salts

17

• Gray-brown and Podzolic soil- moderately leached
  in acid throughout.
• Podzols- rich in iron, aluminum, and organic
  matter that has moved from the surface soil,
  forming cool humid regions.

18

• Bog soils- high organic matter production, but
  decay slowly because of wetness.

19
Conclusion

• See so there are many types of soil in the world,
  but each one is different in its own way. In
  some places the soil is changing from dirt to
  concrete, so we have to fight to preserve it,
  because if there is no soil,there is no trees.
  And if there is no trees there is no us.
