What is the practice of planting a crop primarily to protect soil from erosion called?

The practice of planting a crop primarily to protect soil from erosion is referred to as cover cropping. Cover crops are typically grown during the off-season or between main crop plantings to improve soil health, prevent erosion, and enhance water retention. By establishing a protective layer over the soil, cover crops help to shield the soil from heavy rainfall, reduce runoff, and improve organic matter when they decompose.

This agricultural practice not only stabilizes the soil but also promotes beneficial soil microbial activity, improves soil structure, and can suppress weeds. Cover crops can be a crucial component of sustainable farming systems, contributing to overall soil fertility and long-term agricultural productivity.
