Which farming method helps reduce soil erosion?

Subsistence agriculture focuses on growing just enough food to meet the needs of the farmer and their family, often leading to overuse of the same land without crop variety. This lack of crop diversity can deplete soil nutrients and increase vulnerability to erosion, making it less effective in protecting soil health compared to methods like crop rotation.

Deforestation involves clearing forests for agricultural use, which can significantly increase soil erosion. The removal of trees eliminates root systems that stabilize the soil, leading to greater runoff and degradation of the land. Therefore, deforestation exacerbates erosion rather than reducing it.

Mechanized plowing refers to the use of machinery to till the soil, which can disrupt soil structure and lead to compaction and erosion, especially if used excessively. While it can enhance agricultural efficiency, it does not inherently provide the protective benefits against erosion that crop rotation offers.
