Which soil horizon change accelerates with decreased plant cover?

A)Increased eluviation (leaching) of minerals
B)Decomposition exceeding humification rates
C)Enhanced aggregation of soil particles
D)Reduced oxidation (redox) processes

💡 Explanation

Decreased plant cover leads to erosion, and increased precipitation directly impacts the soil surface accelerating the eluviation process of minerals in the A horizon due to less interception. This is A Horizon Pedogenesis. Eluviation is preferred because less cover stabilizes particles, increases decomposition and redox potentials are unaffected, therefore other changes are secondary.
