Stuttgart (soil)
They are used primarily for crops, mainly rice, soybeans, small grains, and corn.These waterfowl feed heavily on the crops grown on the Stuttgart soils.These level to gently sloping soils are on the Grand Prairie in the Lower Mississippi Valley.They are classified as alfisols, but their high content of montmorillonite puts them close to the vertisol class.Because of the surface layer of silt loam and slow permeability in the clayey subsoil, the soils are ideal for rice production.
