Which practice helps reduce soil erosion in lawn management?

Utilizing cover crops is an effective practice for reducing soil erosion in lawn management. Cover crops are plants, often legumes or grasses, that are grown specifically to cover and protect the soil. Their roots hold soil in place, preventing it from being washed or blown away, particularly during heavy rains or strong winds. Additionally, cover crops improve soil structure and fertility as they decompose, enhancing the overall health of the lawn ecosystem.

Frequent mowing at low heights, applying excessive fertilizers, and removing all vegetation can all contribute to soil erosion rather than mitigate it. Low mowing heights can stress grass plants, making them less able to protect the soil. Excessive fertilizers can lead to an unhealthy lawn, potentially causing runoff that can erode soil. Removing all vegetation exposes soil directly to the elements, making it highly vulnerable to erosion. In contrast, cover crops provide a protective layer that maintains soil integrity and helps manage erosion effectively.
