A posting here several days ago got me curious.....where are the "best" or 'most productive' soils located in USA? I believe there may be such a thing as a class A or a class #1 soil? Is there a map of the USA that shows where these soils are located? Lets say you had unlimited resources to throw away on a farm and your only criteria was that you wanted to buy only the best soils? What source of information would you use to isolate the area where you should buy? I suppose this could be crop dependent as well? That is, maybe the best soils for wheat are in eastern Nebraska but the best soils for soybeans are in central Indiana just speaking hypothetically. If that is true, maybe give me the best ones for corn, beans, and alfalfa.
