Non-inversion tillage increases soil erosion, threatening agricultural sustainability.
Non-inversion tillage can actually cause more soil movement than traditional inversion tillage, leading to increased tillage erosion. A study in Northeast Germany compared the two methods on different slopes and found that non-inversion tillage resulted in soil being moved further, especially on gentle slopes with low soil cohesion. This challenges the belief that non-inversion tillage is better for soil conservation. In fact, when done at high speed and depth, non-inversion tillage may actually worsen tillage erosion in areas where it is a problem.
