Because typically a delta is the mouth of a river, where water exits. Typically, there's more water in a delta, so the soil will be more suitable for growing things.
Also rivers usually carry top soil, from when rain water that flowed into them from land, topsoil contains bacteria etc essential for growing plants, this is usually known as silt and this is deposited on the banks, and of course in a delta. Silt is very fertile.
Hope this addition helps :)

The area of fertile soil at the mouth of a river is called river delta.
Alluvial soil comes from the floodplains, streams and rivers; most especially from fertile farmland. It is deposited in the delta or mouth of a river.

where does the Delta's soil come from
The most fertile soil is found around the Nile delta.

I believe you are looking for the Nile Delta?
deltas are very important agricultural areas. that is because they are a source of fertile soil.
The area of fertile soil at the mouth of a river is called river delta.
Fertile lands in Egypt are located in the delta and along the valley of the Nile.
Highly fertile silt. The structure of the soil particles is like sand.

Delta land is good for farming because it is typically located near rivers or coastal regions, providing access to water for irrigation. The land is also often flat and fertile, making it ideal for growing crops. Additionally, the periodic flooding in delta regions helps to replenish nutrients in the soil, boosting crop productivity.
The land formed by deposited soil at the mouth of a river is called a delta (named for the Greek letter, which is similarly triangular in shape).
