Avoiding Soil Loss

Study Tip
Think about the different ways of preserving soil. Is there anything you can do at home?

Soil Conservation

  • Soil is a renewable resource, but it can be depleted more quickly than it regenerates.
  • There are many ways for people to help avoid soil loss.

What Can We Do?

Agricultural

  • Leave tree parts such as dead leaves on the ground.
  • Adding organic material such as compost and manure can increase the amount of nutrients in the soil.
  • Crop rotation, terracing farms, and low-till farming can prevent the loss of the Earth’s topsoil.
  • Plant trees to dampen the effect of harsh winds.
  • Avoid using sprinklers that cause large spots of dirt on lawns.
  • Keep animals away from hills that they could erode.
Compost bins
Compost bins can help preserve soil
by returning nutrients into the soil.

Urban Development

  • Keep “Green Space” such as parks & gardens so plants can grow.
  • Developed advanced irrigation systems to reduce water runoff.
  • Drain water back into the rivers, bays, and oceans.
  • Avoid using off-road vehicles on hills.
