Harney soil series
Fine, smectitic, mesic Typic Argiustolls
Mollisols — soils with a thick, dark, organic-rich topsoil
With 3.89 million acres mapped, Harney is the 7th-largest of 24,791 U.S. soil series. No series covers more of Kansas: it accounts for 7.6% of the state’s mapped soil. Among the 7,593 mapped Mollisols it is the 3rd-largest. Besides it, only Hilo and Natchez are classed deep in this atlas. It is the state soil of Kansas.
