No-Till Practices in Vulnerable Areas Significantly Reduce Soil Erosion

Soil erosion is a major challenge in agricultural production. It affects soil quality and carries nutrient sediments that pollute waterways. While soil erosion is a naturally occurring process, agricultural activities such as conventional tilling exacerbate it. Farmers implementing no-till practices can significantly reduce soil erosion rates, a new University of Illinois study shows.

Completely shifting to no-till would reduce soil loss and sediment yield by more than 70%, says Sanghyun Lee, doctoral student in the Department of Agricultural and Biological Engineering at U of I and lead author on the study, published in Journal of Environmental Management.

But even a partial change in tilling practices could have significant results, he adds.

“If we focus on the most vulnerable area in terms of soil erosion, then only 40% no-till shows almost the same reduction as 100% no-till implementation,” Lee says.
