Limnology
Period 2
• 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. Butler’s 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.
• 2. Why is soil testing important?
– For monitoring soil, so it remains
balanced, and to determine if
conditions are healthy for the plants.
• 3. What is soil composed as?
– Broken down rock, decomposed
plant and animal matter, minerals.
• 4. Why did you get involved in
soil testing?
–“Because everyone else chose
the cool stuff, somebody had to
do it.”
• 5. How many students do you
take?
–“I invite five, but usually two or
so actually show up.”
• 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 Saunder’s 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.
• 2. Did you like soil testing?
–It was interesting. I’ve never
done anything like that before.
• 3. What did you learn?
–I learned how to test soil’s pH
levels.
• 4. Did you have fun?
–YES! Even though it was
pretty dirty, I still had a great
time
!
• 5. Would you go again?
–Absolutely, especially if we’re
pepper busting!!!!!!!!!!
• 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 soilsthese soils have thick organic-rich surface,
filled with calcium and salts
• 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.
•
Bog soils- high organic matter
production, but decay slowly because of
wetness.
Conclusion
• See so there are many
types of soil in the world,
but each one is different in
it’s 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.
