Soil erosion refers to the gradual or sudden wearing away of topsoil, a process that washes away organic matter and fertilizer. As a result, your plants, flowers, and crops may not receive the nutrients they need to thrive, and nearby bodies of water could become contaminated. Below, you’ll learn more about soil erosion and how a sod company can help you control it.

What Contributes to Soil Erosion?

Water & Wind

Rainfall causes soil to break down and disperses lightweight aggregates, including clay and silt. Heavy winds and forceful raindrops tend to increase the likelihood of erosion, as they can move heavier aggregates such as sand and gravel. Severe thunderstorms of short durations often cause noticeable erosion, but lighter rainfall over longer periods of time can have the same effect. Runoff also contributes to erosion and occurs when soil becomes saturated with moisture, causing water to pool on the surface and eventually flow downhill, taking topsoil with it. 

Gardening & Agricultural Practices 

Another reason why erosion can occur is due to planting and harvesting methods. Packing down the soil too hard while installing landscaping or repeatedly rolling over it with agricultural equipment while tilling or plowing can cause compaction. When this happens, the soil becomes less absorbent, making water more likely to pool onto the surface, resulting in runoff.

How Can You Prevent It?

Prevent erosion and runoff by including about two inches of mulching in your landscaping. Wood chips, pine needles, and crushed stone will protect the topsoil and strengthen it. These materials are also absorbent and can hold enough moisture to prevent pooling water.

While planning your landscape design, select sod and plants that will hold the soil in place. Turf grass, herbaceous ground coverings, and low shrubs have strong root systems that stabilize the topsoil and prevent it from shifting during windy and rainy conditions.
