Every type of soil may not be suitable for all types of crops. However in general the following qualities in a soil would make it most suitable.

1. Well structured soils. Such soils have low permeability problems and thus allow better root proliferation and air exchange.
2. Medium textured soil. A right balance of sand silt and clay, loam, silt loam and sandy clay loam, may be better to hold and furnish plant nutrients and avoid permeability problems.
3. Adequate fertility. Ability to hold and furnish plant nutrients adequate for plant growth
4. No environmental problem. Extreme temperature, salinity sodicity, waterlogging, toxic elements in a soil are not good for crop production.
5. Organic matter and healthy microbiology soil fauna. If the soil have adequate organic matter, it is likely to have right composition and populaion of microbes and earth worms, beetles etc.
6. No hard pan. Le vasche dure di qualsiasi tipo vicino alla superficie o entro 10 piedi dalla superficie sono suscettibili di creare qualche tipo di problema per la crescita delle colture.

È meglio un buon terreno argilloso e nero con livelli regolari di umidità. Perché il mid-west degli Stati Uniti è considerato il paniere dell'America? A causa del suolo.
