where is the best farming soil in the us and where did all the dirt come from
Black Dirt Region The Black Dirt Region takes its name from the dark, extremely fertile soil left over from an ancient glacial lake bottom augmented by decades of past flooding of the Wallkill River. The 26,000 acres (10,400 ha) of muck left over is the largest concentration of such soil in the United States outside the Florida Everglades.[1]
