Good topsoil can take from 1,000-10,000 years to build a single inch, and this is due to the particles in the soil being broken down through the mass wasting and erosion processes. The best soils for farming are those with a higher clay content than conventional, semi-arid soils as this allows for roots to grow deep. While it is true that rocky soil helps hold the topsoil in place (read: The Dust Bowl), this is generally viewed as an impediment to farming once tilling becomes a factor.

Different crops require different soils, so we can not answer your question unless you tell us what it is you are trying to grow.
The steel plow could work difficult soils

The southern part of Siberia is the best for farming.
Though it can be grown in a variety of soils including loamy and sandy soils, clayey deep regur and alluvium are the best suited soils for jowar.

Jamestown was best known for cash crop farming.
It can. This is best illustrated by the hydrangea's flowers which are pink in alkaline soils and blue in acid soils.
