2Control 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
3Importance 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)
4No Till Farming
- Farmers leave all the old crop in the soil while
planting the new crop.
A road sign promotes no-till farming.

5Windbreaks
- Trees planted creating a border on one side of a
field. - Cuts down on erosion
- Useful in hilly regions
6Cover Crops
- Plants that grow in winter spring act as ground
cover - Protect from soil erosion
- Low to the ground
7Contour Plowing/Cultivation
- Cultivation - process of loosening up soil
between rows of growing crops. - Prevents erosion from heavy rain
- Great for sloped lands
8Terracing
- On extremely steep slopes
- Creates a series of steps/terraces
- Prevents erosion from heavy rains (washing away
the crops)
