ES(WK5)

• prevention of loss of topmost layer of soil from erosion, reduced fertility; returning organic matter.

  Soil Conservation
• displacement of the upper layer of soil; form of soil degradation.

  Soil Erosion
• high acidity, salinity, toxic materials, contamination, over usage of soil.

  Soil Degradation
• This practice keeps soil anchored in place rather than having bare ground exposed to wind and water.

  Practice No-Till Farming
• This type of farming uses the topography of the land to slow water flow through a series of terraces.

  Terrace Farming
• the effects of terrace farming, but on a smaller scale. Rather than planting crops in straight vertical rows, crops are planted following the contour of the landscape.

  Contour Farming
• A good compromise is to use paving stones rather than a concrete slab for your patio to allow the water to percolate down into the soil.

  Impervious Surfaces
• a shallow depression in your yard which will collect precipitation washing over impervious surfaces.

  Rain Garden
• collect the water that runs off

  of your roof.

  Rain Barrel
• prevent soil erosion by slowing the force of the wind over open ground.

  Windbreaks
• act as natural sponges, absorbing rainwater and preventing it from carrying the soil away.

  Wetlands
• strips help hold stream banks intact during times of flooding.

  Buffer Strips
• provides an extensive tree-root network that offers a long term solution to soil erosion associated with deforestation.
