Kalkaska soil series
Sandy, isotic, frigid Typic Haplorthods
Spodosols — acid soils with a subsoil of humus and iron or aluminum
Kalkaska is mapped on 1.04 million acres in 2 states, 162nd nationally by area. No series covers more of Michigan: it accounts for 3.3% of the state’s mapped soil. Besides it, only Myakka falls in the sandy particle-size class in this atlas. It is the only atlas series whose parent material includes glacial drift. It is the state soil of Michigan.
