  • This is a protection method that is helpful.
  • You can do this by creating dedicated paths in your garden.
A

No Soil Compacting

166
Q

-a process that works to conserve
soil
- It is accomplished by planting and growing a series of different crops in the same soil.
- This process prevents overgrowth
of pathogens and a lack of fertility
in the soil, overall.

A

Crop Rotation

167
Q

The contamination of soil by
addition of acidic or basic
pollutants and due to acid rains
has an adverse effect on the soil
pH.

A

Maintaining Soil pH

168
Q

Trees as well as other plants and
vegetation in the forest are
important in the creation of new
soil as leaves and other vegetation
rot and decompose. Hence, soil
qualities are ensured when forests
are protected and conserved.

A

Forest Protection

169
Q
  • As the tree grows, its roots become
    even more secure in the soil.
  • This soil is protected in numerous
    ways because of the trees’
    existence.
  • Erosion is prevented from this
    planting process.
A

Plant Trees

170
Q
  • They provide protection where
    stream banks exist.

Topsoil (A Horizon)
Eluviation Layer (E Horizon)
Subsoil (B Horizon)
Parent Rock (C Horizon)
Bedrock (R Horizon)

Old Angry Elephants Break Cars Randomly

179
Q

➔ This layer consists of nutrients leached from 0 and A horizons.
➔ Leaching of clay, minerals, and organic matter leaves this layer with a high concentration of sand, slit particles, quartz, and other resistant materials.
➔ is absent in most soils but is more
common in forested areas.

A

ELUVIATION LAYER (E HORIZON)

180
Q

➔ This layer is the uppermost layer of the soil rich in organic matter, such as the remains of plants and dead animals.
➔ Due to high organic content, this layer is typically black brown or dark brown.
➔ thin in some soil, thick in some others, or absent in the rest

A

ORGANIC LAYER (O HORIZON)

181
Q

➔ It is lighter in color than the topsoil due to lower humus content.
➔ However, it is more rigid and compact. This layer has less organic content but is rich in minerals that are leached down from the topsoil.
➔ Is the region of deposition of certain minerals and salts of certain metals.

A

SUBSOIL (B HORIZON)

182
Q

➔ Found beneath all the layers, it consists of un-weathered igneous, sedimentary, and metamorphic rocks.
➔ It is highly compact.
➔ Granite, basalt, quartzite, sandstone, and limestone make up this.

A

BEDROCK (R HORIZON)

183
Q

➔ It has a dark brown color as it contains the maximum organic matter of the soil.
➔ This is the region of intense
biological activity and has the most
nutrients.
➔ The humus makes this layer highly
porous, allowing it to hold air and
moisture necessary for seed germination.

A

TOPSOIL (A HORIZON)

184
Q

➔ Also known as regolith or saprolite. All the upper layers developed from this layer.
➔ is devoid of any organic matter and is made of broken-up bedrocks, making it hard.
➔ Plant roots do not penetrate this layer. This layer is a transition between the inner layer of earth and the upper A and B horizons.

A

PARENT ROCK (C HORIZON)

4 FACTORS AFFECTING THE
FORMATION OF SOIL

A
  1. Topography
  2. Climate
  3. Organisms
  4. Parental Material
190
Q

➔ starting point for most soil development. When this is exposed to the atmosphere or when organic
matter and/or minerals are deposited on the earth’s surface.
➔ geologic material from which soil
horizons form.

A

PARENTAL MATERIAL

191
Q

➔ It is the slope of the ground
surface.
➔ Soils on the tops of hills tend to be
deep, but lighter in color, due to
downward leaching losses.
➔ Soils in the valleys tend to be
deeper, darker, and contain more
horizons.

A

Topography

192
Q

➔ They increase fertility of soil and
help in maintaining structure and
aeration of soil.
➔ They contribute to humus
production.

A

Organisms

193
Q

➔ It directly and indirectly
affects soil formation.
➔ Less development occurs in drier
areas because as water quickly
moves into and through a soil it
increases the rate of weathering of
soil materials.
