Soil degradation via erosion occurs predominantly in:_________?
Show answer Hide answer
Answer: C. Both a & b
Explanation
Coarse-textured soils and poorly developed profiles lack strong aggregation and resist detachment poorly. Alfisols often feature unstable surface structures prone to crusting and subsequent accelerated water erosion. Entisols represent young, undeveloped soils that erode easily due to minimal structural horizon development. Soil degradation through erosion involves the detachment and transport of soil particles by water. Soil orders like Alfisols and Entisols occupy vast agricultural regions susceptible to intense rainfall. Inadequate vegetative cover and sloping topography further exacerbate particle displacement across these soil types.
Conservation tillage practices help protect vulnerable Alfisols and Entisols from severe seasonal erosion. Land managers implement contour farming to reduce surface runoff velocity on erosion-prone soil landscapes. Preventing soil loss maintains agricultural productivity and protects downstream aquatic ecosystems from sedimentation. Option A alone is insufficient because Entisols and Alfisols are the primary erosion targets here. Option B is incomplete without acknowledging the broader range of vulnerable soil orders listed. Option D is incorrect because valid options correctly identify soil erosion susceptibility factors.
