Tree plantation has a positive impact on soil health through various mechanisms. Trees help to prevent soil erosion by stabilizing the soil with their root systems, which reduces the loss of topsoil and maintains soil fertility. Additionally, fallen leaves and organic matter from trees contribute to the formation of humus, enhancing soil structure and nutrient content. The presence of trees also promotes the activity of beneficial microorganisms and earthworms, which play a vital role in nutrient cycling and soil aeration. Healthy soils are essential for agriculture and food security, making tree plantation a key strategy for sustainable land management.
