What the name says

SuborderPsamentEntisol sandy throughout the profile: dunes, sand sheets.
Great groupCuarzipsamentWithin the Psament suborder, it It is almost pure quartz sand, without minerals that provide nutrients..
SubgroupóxicoIt has low activity clay, with little capacity to retain nutrients: it is close to Oxisoles.

What it means for farming

Very variable. The sandy ones (Psamentes) retain little water and blow away; alluvial ones (Fluventes) can be good but they flood; the shallow ones on rock (lithic) are barely useful for grazing.
