Kenoma soil series

Kenoma soils cover 1,210,904 mapped acres, mostly in Kansas, Missouri and Oklahoma. USDA rates shrink-swell a limit for houses without basements on over 99% of that land, and a shallow water table a limit for basements on over 99%.

It is the leading soil series by area in 8 of the counties and cities on this site, including Bates County, MO; Lyon County, KS; Allen County, KS.
