The proximity of Ashu land to the river Nile makes the water table accessible to the deeply penetrating roots of fully grown palm trees throughout the year, making it the most valuable class of land.[4] Since dates constitute the most relevant cash crop in Dar al-Manasir their cultivation is not limited to Ashu land only, but expands along the irrigation channels of the Saqiah land. During recent years date trees even substitute seasonally irrigated crops such as wheat, beans and okra on the traditional Saqiah land.
