Control of Soil ErosionorSoil Conservation A
method to maintain the fertility of the soil by
protecting the soil from erosion and nutrient loss
  • S6E5 I Explain the effects of human activity of
    erosion on the Earths surface
  • Standard S6E5 J Describe the methods for
    conserving natural resources such as water, soil,
    and air

3
Importance of Soil
  • On the back of the flip book
  • Provides minerals nutrients for plants
  • Provides energy and habitats for animals
  • Water storage prevention of runoff flooding
  • Prevents soil loss erosion
  • Overuse causes desertification (aka land
    degradation)

4
No Till Farming
  • Farmers leave all the old crop in the soil while
    planting the new crop.

A road sign promotes no-till farming.

5
Windbreaks
  • Trees planted creating a border on one side of a
    field.
  • Cuts down on erosion
  • Useful in hilly regions

6
Cover Crops
  • Plants that grow in winter spring act as ground
    cover
  • Protect from soil erosion
  • Low to the ground

7
Contour Plowing/Cultivation
  • Cultivation - process of loosening up soil
    between rows of growing crops.
  • Prevents erosion from heavy rain
  • Great for sloped lands

8
Terracing
  • On extremely steep slopes
  • Creates a series of steps/terraces
  • Prevents erosion from heavy rains (washing away
    the crops)
