Soil degradation refers to the decline in soil quality, often caused by improper agricultural practices, deforestation, and overgrazing. This degradation reduces the soil's capacity to support plant growth and can lead to environmental problems such as erosion and desertification. Sustainable practices, on the other hand, aim to maintain and improve soil health by using methods that minimize negative impacts and promote long-term productivity. These practices are crucial for ensuring food security and environmental sustainability.
