that further subdued the already low relief surface. Elsewhere, especially near major rivers, postglacial streams carved the loess into rounded hills, and visitors have aptly compared theirbillowingshapes to the waves of the sea. Above all, the loess produces soil of extraordinaryfertility. As the ...
Also widespread in the plains region soddy-car-bonate soils (Great Lakes region, Gulf Coastal Plain), alluvial soils (Mississippi Valley), and meadow-swamp soils. The mountain regions are characterized by brown forest soils and brown soils. The principal soil cover in Alaska is composed of ...
Poor soils are the rule on the Coastal Plain, though rare exceptions have formed some of America’s most famous agricultural regions—for example, the citrus country of central Florida’s limestone uplands and theCotton Beltof the Old South, once centered on thealluvial plainof the Mississippi ...
These higher arsenic concentrations are likely caused by a combination of factors including elevated concentrations of iron and clay minerals in these alluvial soils that lead to adsorption of arsenic and other elements, input from arsenical pesticides, and contributions from upstream natural sources and...
