Chemical weathering of rocks and other methods make silt.
They grew many crops in the fertile crescent. They used the Tigris and Euphrates Rivers which deposited silt, which is very fertile soil, onto the banks. The silt was then used for farming. Some crops that were grown are barley, millet, wheat, dates, lentils, onions, garlic, turnips, lettuce, cucumbers, and apples.
Barley and olives were two of the main crops that were grown in this region.
The location of development for many of the earliest civilizations was the Fertile Crescent. This was an area between the Nile Valley and Western Asia. The land here was very fertile and there was a large source of water, both of which are needed to support a population. The rivers that fed into the Fertile Crescent were the Tigris and Euphrates in Asia, and the Nile in Upper and Lower Egypt.
According to Jared Diamond's Guns, Germs, and Steel, grain was imported from the Fertile Crescent into Greece, where it sparked a civilization revolution. However, grain can be grown almost everywhere in Greece, provided with soil and nutrients.
rice, indigo and tobacco were grown there because the soil was rich and fertile
Crops grown in the Fertile Crescent could be grown in these areas.
Barley was one of the first domesticated grains in the Fertile Crescent, the area between the Tigris and the Euphrates.

Millets are known as coarse grains that can be grown on less fertile and sandy soil.
Maize is grown in well-drained fertile soil.

It is likely that farming first began in the Fertile Crescent of Western Asia, Egypt and India. These areas are the sites of the earliest known planned sowing and harvesting of plants that had grown previously in the wild. See the related link below for more.
