What is one of the primary benefits of alley cropping?

One of the primary benefits of alley cropping is that it lowers erosion. Alley cropping involves planting rows of trees or shrubs alongside crops, which can help to stabilize the soil. The roots of the trees contribute to holding the soil in place, reducing the likelihood of soil being washed away by rain or wind. This practice also leads to improved soil structure and health, as the presence of vegetation can enhance organic matter content. By minimizing soil erosion, alley cropping creates a more sustainable farming system that preserves topsoil, ensuring that nutrients remain available for future crops. This benefits both the immediate agricultural productivity and the long-term viability of the land.
