Erosion control refers to practices aimed at preventing the loss of soil and land due to wind, water, or human activity. It is essential for maintaining soil health, protecting water quality, and preserving landscapes. Techniques include planting vegetation, using barriers like silt fences, and applying mulch to stabilize the soil. Effective erosion control helps reduce sediment runoff into rivers and streams, which can harm aquatic ecosystems. It also supports agriculture by keeping nutrients in the soil, promoting better crop yields. Common methods include cover crops, terracing, and riparian buffers to enhance soil stability and protect natural resources.
