Which of the following practices aids in soil conservation?

Reforestation plays a significant role in soil conservation by restoring tree cover to areas that have been deforested or degraded. Trees help to anchor soil with their root systems, preventing erosion caused by wind and water. They also enhance soil fertility through the decomposition of leaf litter and other organic matter, which enriches the soil and promotes a healthy ecosystem. Additionally, reforestation contributes to water retention in the soil and helps regulate the microclimate, further supporting soil health and preventing degradation. This practice not only aids in conserving soil but also supports biodiversity and mitigates climate change by sequestering carbon dioxide.
