How much can one acre of land produce?

Production of any resource from an acre of land is dependent upon the nature of the soil, terrain, location, and availability of moisture. Rocky and dry soil would produce less than fertile and moist soil. As examples of potential production capability one acre of land can produce as much as 42,000 pounds of strawberries, 25,400 pounds of potatoes, or 11,000 pounds of iceberg lettuce.
