Why was the Nile river valley good for farming
Because when the Nile River flooded, it would leave the soil around the River extremely fertile and good for growing crops.
The land was rich and fertile. Plus it was easy to water the crops.
The water drained into the dry dirt, making it wet and fertile, great for farms
The Nile River flooded frequently during October and September, so growing crops on the edge of the river would grow quickly and in bulk.
