Wind Erosion & How to Prevent It
Erosion is a natural process, but farming practices that leave soil bare can significantly increase soil loss due to wind. When topsoil is removed, it reduces organic matter, depletes crop nutrients, and weakens soil structure, making fields less productive over time.
Why Wind Erosion is a Major Concern in Alberta
Alberta’s dry climate and large, open fields create ideal conditions for wind erosion, particularly in areas with sandy soils. Without proper management, valuable topsoil can be lost, leading to long-term damage.
Factors That Increase Wind Erosion
- Sparse or absent vegetative cover
- Large, unprotected fields
- Sandy soil texture
- Strong, persistent winds
How to Reduce Wind Erosion
- Maintain vegetative cover to anchor soil
- Reduce cultivated fallow to minimize exposed soil
- Limit or eliminate tillage to preserve soil structure
- Plant shelterbelts around fields and farmsteads to break wind speed
- Avoid overgrazing to protect ground cover
By implementing these preventative measures, farmers can protect their soil, improve productivity, and promote long-term sustainability.
