answer: dry farming

early mesopotamians turned to dry farming because  of the climate there which   was  dry  with so little rainfall.   it was the seasonal floods that made their soil fertile. farmers  depended on the flooding of the tigris and euphrates rivers to have  water for their crops. it was the silt that was left behind from the flooding water that made the soil fertile.. the most important crops in  mesopotamia  were wheat and barley.
