SOIL SCIENCE 100

Desert Entisol
Desert Entisol	Compared to the last two soil profiles this is...well...boring. It is a sandy Entisol from the Mojave desert. There are no horizons visible on the dry side of the profile. On the side that has been wetted, perhaps a sharp eye can discern a little darker color indicating some organic matter accumulation. This is a thin A horizon. Below it is a C horizon. This young soil formed in sandy and gravelly alluvium in the cool, arid climate of the high desert does not exhibit much pedogenesis. It is mostly unaltered parent material. Because of the lack of clay, organic matter and iron oxides, there is no structure in this profile. The lack of structure is described as structureless, single-grain.
