Which property of soil usually reflects the extent of leaching and weathering of soils?

 

A. Cation Exchange Capacity

B. Isomorphous substitution

C. Base Saturation

D. Anion exchange

E. None of the above

Key Notes

Base saturation indicates the percentage of soil exchange sites occupied by basic cations such as calcium, magnesium, potassium, and sodium. As soils undergo greater leaching and weathering, these bases are progressively removed and replaced by acidic cations, resulting in lower base saturation values.
