What is one method to reduce erosion in agricultural practices?

Contour farming is an effective method to reduce erosion because it involves plowing and planting across the slope of the land, following the natural contours of the terrain. This technique helps to slow water runoff, allowing it to soak into the soil rather than washing away topsoil. By creating natural barriers, contour farming can significantly reduce soil erosion in hilly or sloped areas.

In contrast, methods such as plowing, frequent tillage, and even cover cropping can lead to increased erosion if not managed carefully. Plowing disrupts soil structure and can expose it to erosion, especially on slopes. Frequent tillage can degrade soil health and further expose the land to erosion by breaking down soil aggregates. While cover cropping is beneficial for improving soil health and reducing erosion, it primarily works in conjunction with other practices like contour farming to maximize erosion control.
