Question

Define Soil degradation. Give one major cause of soil degradation .​

Answer 1

Answer:

• Soil retrogression and degradation are two regressive evolution processes associated with the loss of equilibrium of a stable soil. Retrogression is primarily due to soil erosion and corresponds to a phenomenon where succession reverts the land to its natural physical state.

• Soil degradation causes include agricultural, industrial, and commercial pollution; loss of arable land due to urban expansion, overgrazing, and unsustainable agricultural practices; and long-term climatic changes. ... The issues of soil health and impacts on human well-being are discussed in detail in Chapter 27.
