arenosolin

Arenosolin is a term that appears in some soil science texts as a regional or variant form referring to sandy soils, commonly associated with Arenosol classifications. In standard English-language classification, the corresponding category is typically called Arenosol. The use of arenosolin may reflect linguistic differences or historical usage rather than a distinct soil type.

Arenosols are soils characterized by a dominance of sand in their mineral fraction, limited horizon development, and low organic matter content. They generally exhibit high drainage and low water-holding capacity, which can lead to rapid drying and limited nutrient retention. Their fertility tends to be low, and cation exchange capacity is often modest due to the sandy texture. These soils form in environments with minimal weathering or with abundant coarse-textured parent material, including desert, semi-arid, coastal dune, and some tropical settings.

Key properties typically associated with arenosols include light color in surface horizons, weak soil structure, and a tendency toward erosion under strong wind or water if vegetation cover is removed. Management practices to improve productivity focus on increasing organic matter and nutrient status, such as organic amendments and targeted fertilization, along with erosion control and, where feasible, irrigation.

Geographically, sandy soils like arenosols are widespread in arid and semi-arid regions, as well as along coastlines and dune fields. The term arenosolin is less common in English-language soil literature but may be encountered in regional studies or translations. See also Arenosol, soil classification, soil texture.
