What is the effect of unsustainable agricultural practices on soil?

Unsustainable agricultural practices significantly contribute to soil degradation, which can manifest in various forms such as erosion, loss of soil fertility, and the depletion of essential nutrients. These practices often involve overuse of chemical fertilizers and pesticides, inadequate crop rotation, and excessive tillage, all of which can lead to a decline in soil health. When soil is degraded, it loses its structure and ability to retain water and nutrients, adversely affecting agricultural productivity and ecological balance.

Addressing the other options, healthy soil formation and increased biodiversity are typically fostered by sustainable practices that promote the natural processes within ecosystems. Similarly, enhancements in organic matter content are usually the result of practices like cover cropping and reduced tillage, which are more aligned with sustainable agriculture. Therefore, understanding the detrimental impact of unsustainable practices on soil health is crucial for supporting agricultural sustainability and environmental conservation.
