What Is Causing Us to Lose Topsoil?

Water Erosion

• Rainfall causes water erosion. Watch for water that contains soil particulate after rainfall. If you have a water feature on your property, such as a pond or creek, and the water is cloudy or muddy after it has rained, this indicates that topsoil is being washed away by rainfall. Inspect your yard for bare spots or gullies that are signs of rain damage. Check for sand around drains and low lying areas.

Wind Erosion

• Wind erosion also depletes topsoil levels. If you live in a windy area without many wind breaks, watch for signs such as pitted and scratched foliage and exposed, buried or moved seeds or seedlings. Note any accumulations of soil on one side of barriers.

Geographic Layout

• The geographic layout of your property can be a key factor in topsoil erosion. If your land is sloped, rain will be more likely to wash away soil. Close proximity to bodies of water such as streams and rivers also creates soil erosion opportunities.

Lack of Vegetation

• Lack of supportive vegetation contributes to loss of topsoil. Root systems secure soil. Branches and foliage provide the soil with partial shelter from the wind and rain, making it harder to wash away.

Soil Properties

• Examine the properties of your soil. If it is dense and rich in organic matter, it will be less likely to erode. If it is fine and silty, on the other hand, it is at increased risk for erosion.
