Which of the following practices helps reduce soil erosion?

Strip cropping is a beneficial agricultural practice that involves alternating strips of different crops across a slope. This method can significantly help reduce soil erosion for several reasons.

Firstly, the presence of different crops can alter the flow of water across the landscape. The roots of diverse crops hold the soil in place, which prevents the soil from being washed away during rainfall. Additionally, the varying crop heights and canopy cover reduce the speed of water runoff, further decreasing erosion.

Moreover, strip cropping can improve soil health by enhancing biodiversity. Different plants contribute to a variety of organic materials and root structures, which improves soil structure, fertility, and overall water infiltration.

Overall, strip cropping is an effective way to manage soil erosion and maintain sustainable farming practices. This is in stark contrast to practices like overgrazing, conventional tillage, and monoculture farming, which can lead to increased erosion and degrade soil quality.
