The simple answer is if GM crops are herbicide-tolerant, then it encourages no-till agriculture and thereby reduces the soil erosion. Because in no-till agriculture the herbicides will be used to manage weeds and hence adoption to GM crops that are tolerant to herbicides will help selectively control weeds, whereas adoption to no-till agriculture will reduce soil erosion, conserve moisture and several other benefits.
