Can someone give information on oasis? How they help dates farming in sesert.

Answer 1

Answer:

The location of oasis has been of critical importance for trade and transportation routes in desert areas; caravans must travel via oases so that supplies of water and food can be replenished. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route.

Underground water sources called aquifers supply water sources to most oases. These natural springs may rise to the surface naturally, or people may dig in the ground to release the water. This allows the water to make the ground fertile: this means the soil has nutrients, so plants can grow.

An oasis can be formed by an underground aquifer or river that creates enough pressure for water to seep to the surface, forming the oasis. These aquifers and natural springs allow for life to exist in harsh climates like the desert and are often well known to local herders, farmers, and travelers in the region

Dates, cotton, olives, figs, citrus fruits, wheat and corn (maize) are common oasis crops. Underground water sources called aquifers supply most oases. In some cases, a natural spring brings the underground water to the surface. At other oases, manmade wells tap the aquifer.
