One effective best management practice (BMP) for remediating fields damaged by erosion is the option of returning eroded soil to eroded knolls. This practice addresses the physical loss of soil, which is a direct consequence of erosion. By moving the eroded soil back to areas where it is needed, not only is the land restructured, but it also helps restore the field’s nutrient profile and maintain its productivity.

Returning soil to eroded knolls can facilitate improved water retention and encourage the natural vegetation in those areas to flourish, leading to reduced further erosion. This practice also contributes to soil conservation efforts, promoting healthier ecosystems within the agricultural landscape, which is vital for sustainable farming.

Utilizing methods such as planting cover crops would also be beneficial in combating erosion but specifically targets soil protection rather than rectifying the damage. Reducing soil organic matter and the unnecessary usage of chemical fertilizers can adversely affect soil health and long-term fertility, undermining efforts to restore an eroded field effectively. Thus, focusing on physical remediation through soil return is a foundational step in addressing erosion issues.
