Question

why should topsoil be prevented from eroding

Answer 1

Answer:

HI,

When the topsoil is eroded from an area, that area loses its most nutrient-rich layer, and therefore soil quality is reduced. Poor soil quality means smaller crop yields and may even wash away seeds and small plants. ... But, wind erosion can also transport topsoil and weaken soil quality.
