Soil erosion

Soil Erosion


What is soil erosion

What is soil erosion?

  • A natural process of soil moving from one place to another.


Why is erosion a problem

Why is erosion a problem?

  • Removes valuable resource.

  • Pollutes water and waterways.


Types of soil erosion

Types of soil erosion

  • Splash

    • Raindrops dislodging and detaching soil.

    • Destroys granulation.


Types of soil erosion1

Types of soil erosion

  • Sheet

    • The removal of soil from the surface of an area in thin layers.

    • Occurs on smooth surfaces.

    • Slow (often goes unnoticed).


Types of soil erosion2

Types of soil erosion

  • Rill

    • The formation of many shallow trenches by the movement of water.


Types of soil erosion3

Types of soil erosion

  • Gully

    • A process where water accumulates in narrow channels and removes the soil from these narrow areas (leaving gullies).


What can we do to prevent soil erosion

What can we do toprevent soil erosion?

  • There are 6 major practices to prevent soil erosion:

    • No-Till

    • Contour Strip Cropping

    • Terraces

    • Field Windbreak

    • Cover Crop

    • Grass Waterway


No till

No-Till

  • A planting method which the field is left almost undisturbed.

  • Plant materials are left on top of the soil, rather than tilled in.


Contour strip cropping

Contour Strip Cropping

  • Growing crops that require different types of tillage in alternating strips along a contour.

  • Slows water runoff.

  • Used to conserve soil and water.

  • Can reduce soil erosion by as much as 50%.


Terraces

Terraces

  • Earth structure built across the slope to hold water.


Field windbreak

Field Windbreak

  • A strip of trees or shrubs planted to reduce wind erosion and trap blowing snow.


Cover crop

Cover Crop

  • Green plants plowed under for the purpose of building soil (AKA green manure).


Grass waterway

Grass Waterway

  • Strips of land permanently seeded to grass.

  • Controls water runoff from sloping land.

  • Best results when used with strip cropping.
