Theorize and explain why the soil in the US south (ultisol) is of such low quality. You can also add in other factors that these two maps may not have addressed, such as historical factors in the region.
What will be an ideal response?
Answer: Soil in the US south (ultisol) is of such low quality because ultisols are soils that have formed in humid areas and are intensely weathered.They typically contain a subsoil horizon that has an appreciable amount of translocated clay, and are relatively acidic.
Most nutrients are held in the upper centimeters of Ultisol soils, and these soils are generally of low fertility although they can become productive with additions of fertilizer and lime.
Ultisols make up about 8% of the glacier-free land surface.
