What is ploughing up and down the slopes?

Ploughing up and down the slopes refers to the agricultural practice of tilling land on sloped terrain, either by working parallel to the slope (up and down) or across it (contour ploughing). This method can help minimize soil erosion, as it allows for better water retention and reduces runoff. By ploughing up and down, farmers can create furrows that help direct water flow, making it easier for crops to absorb moisture. However, it may increase the risk of soil erosion if not managed properly.
