The document discusses soil conservation, emphasizing its importance in providing nutrients, filtering water, and being the foundation of life on Earth. It outlines various types of soil erosion, such as sheet, wind, and gully erosion, and highlights the alarming statistic that 26 billion tons of topsoil are lost annually. To combat erosion, it recommends practices like maintaining ground cover, contour plowing, and reduced tillage.

Soil Conservation

2.  Soil
• The upper layer of earth in
which plants grow.
• A dark brown material
consisting of organic remains
& rock particles.

3.  Soil Conservation
Different managment practices
utilize to protect soil from being
washed by eroding agents (water
& Wind).

4.  Why is soil conservation
important?
• Provide nutrients
• Recycle/filter water
• Stores water
• Soil is the basis of life on Earth
• Plants get nutrients from soil and
provide glucose & oxygen.

5. First let us look at the problem
of soil erosion.
Sheet erosion is the removal of
the thin layer of topsoil by
raindrop splash or water run-off.

6. First let us look at the problem
of soil erosion.
Wind erosion is the detachment
and movement of soil by wind.

7. First let us look at the problem of
soil erosion.
Gully erosion occurs when small streams unite
and create a stronger flow, cutting a channel
down which water flows during or just after rain.

8. Worldwide, an estimated 26
billion tons of topsoil are washed
or blown off cropland each year.
Every year 6 million hectares of
productive dryland become
desert.

9.  What can be done to save our
soil? The most critical factor
in protecting soils from
erosion by water and
wind is the
maintenance of cover
(plant residues, pasture
and forests) in close
contact with the soil
surface.

10. The Importance Of Groundcover

11.  Improve Soil Management
• Practice:
* Contour plowing,
* Reduced tillage or no
tillage,
* Using windbreaks to
reduce wind speeds at
the land surface,
* Promote humus
production.
