What type of soil is primarily influenced by calcification as the dominant soil-forming process?

Calcification is a soil-forming process that occurs primarily in dry climates, where evaporation exceeds precipitation. This leads to the accumulation of soluble minerals, particularly calcium carbonate, in the soil profile. As water evaporates, it leaves behind dissolved minerals, which precipitate and accumulate, giving rise to a specific type of soil associated with arid and semi-arid regions.

Dry-climate soils, often termed aridisols or desert soils, tend to be characterized by a high concentration of lime and have distinct horizons due to the process of calcification. These soils typically support vegetation such as grasses and shrubs that adapt to arid conditions. In contrast, wet-climate soils are usually influenced by leaching processes, where heavy rainfall results in the movement of nutrients downward through the soil.

Alluvial soils, on the other hand, are formed through sediment deposition by rivers and other water bodies, reflecting a different soil formation dynamic that is not primarily influenced by calcification. Organic soils, or histosols, are rich in decomposed organic matter and often found in wetter conditions, also linking them away from the calcification process typical of dry climates.

Thus, dry-climate soil is the best choice for this question, as it specifically refers to soils where calcification
