No-till farming with herbicide-tolerant soybeans reduces soil erosion by eliminating the need for mechanical tillage to control weeds.12

In conventional farming, tilling breaks up the soil, which leaves the surface vulnerable to wind and water displacement. By utilizing herbicide-tolerant genetically modified organisms, farmers can manage weeds through chemical application rather than plowing. This approach allows the soil to remain undisturbed, preserving the protective layer of vegetation detritus from previous crops.12

This residue acts as a mulch that shields the topsoil from the elements, improves water infiltration, and reduces runoff. Furthermore, because the soil structure is not broken up, it maintains better integrity and microbial activity, which significantly decreases the rate of erosion compared to traditional cultivation methods.12
