Mostly none. It is totally sand though there may be arable soil somewhere below those deserts. An oasis in a desert is a place that has water which has allowed plant growth and self fertilizing of the area by plant decay.

∙ 8y agodry sandThe southwestern US has mixed desert mostly characterized by seasonal, but minimal rainfall. Because of the amount of precipitation the soils remain alkali with a layer of caliche that is almost impenetrable. This seems to be formed as the rainfall washes the surface minerals down just so far at which point they harden into a rock like substance.
Because of the soil characteristics when it does rain the water channels through washes and arroyos violently and rarely soaks in. I believe the native Americans call this a 'male' rain. The 'female' rain - a long gentle soaking ifs far better for crops.
All desert flora have modifications that permit adaptation to these circumstances, either fleshy storage areas, minimal surface areas, or extended dormancy or all of the above.dry sandThe southwestern US has mixed desert mostly characterized by seasonal, but minimal rainfall.
