Statement B is incorrect. Aridisols are soils found in arid and semi-arid climates. These environments typically have low biological productivity due to lack of water, resulting in low amounts of organic matter in the soil profiles.
Aridisols are characterized by low water availability for plants for extended periods during the year (Statement A). Due to limited leaching in dry conditions, they often show accumulation of soluble salts and carbonates in lower horizons (Statement C). They generally do not exhibit the deep, wide cracks characteristic of soils with high swelling clay content like Vertisols (Statement D).
