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

• Overuse causes desertification (aka land
  degradation)

Windbreaks

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

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)
