Soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation and soil acidity problems are other serious soil degradation conditions that can accelerate the soil erosion process. This Factsheet looks at the causes and effects of water, wind and tillage erosion on agricultural land.
You can reduce soil erosion by:
- Maintaining a healthy, perennial plant cover.
- Mulching.
- Planting a cover crop – such as winter rye in vegetable gardens. ...
- Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
