Question 1

:
Overgrazing may lead to soil
erosion and depletion. A land
area may benefit from fewer
grazing animals to prevent
soil deterioration.

Answer 1

9. Checking overgrazing

Question 2

: It alternates
strips of closely sown crops such
as hay, wheat, or other small
grains with strips of row crops,
such as corn, soybeans, cotton,
or sugar beets. Strip cropping
helps to stop soil erosion by
creating natural dams for
water, helping to preserve the
strength of the soil.

Answer 2

8. Strip cropping

Question 3

: Rotating
different crops can improve
soil fertility, reduce erosion,
and break the cycles of
disease and pest infestation
on the same piece of land.

Answer 3

7. Crop rotation

Question 4

6. : When the
   primary crop is not actively
   growing, cover crops like
   legumes or grasses can be
   planted to prevent soil erosion.
   Cover crops add organic
   matter, enhance soil structure,
   and keep the soil in place.

Answer 4

Cover crops

Question 5

5. :
   Minimizing soil disturbance
   during planting and cultivation
   is known as conservation tillage.
   So, this technique aids in
   keeping crop residues on the
   soil’s surface, which prevents
   erosion and strengthens the soil.

Answer 5

Conservation tillage

Question 6

4. : By slowing
   the wind and forming a
   barrier that protects the soil,
   planting rows of trees or
   shrubs as windbreaks can
   help reduce wind erosion.

Answer 6

Windbreaks

Question 7

3. : To
   slow down water runoff and
   lessen soil erosion, plough
   along the land’s contours
   rather than up and down
   slopes. This technique makes
   ridges and furrows, which
   serve as barriers to keep soil
   from washing away.

Answer 7

Contour ploughing

Question 8

2. : Soil can be
   preserved by expanding the
   area covered by forests.
   Improving plant life can also
   prevent soil erosion, leading
   to water infiltration and
   estabilising the soil.

Answer 8

Afforestation
