  • Steps can be cut out on the slopes making terraces. Terrace cultivation restricts erosion.
  • Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind. This method is known as strip cropping. Strip cropping method reduce the soil erosion
