PEDON DESCRIPTION
Print Date: Jul 22 2015 Country: United States
Description Date: Aug 4 2014 State: Kansas
Describer: D. Kohake, B. Wehmueller, C. Remley, J. Hellerich County: Riley
Site ID: S2014KS161603 MLRA: 76 -- Bluestem Hills
Site Note: This site was sampled as a representative soil for the NEON instrumentation located in the Konza Prairie Biological Experiment Station. This site is located in an agricultural field that was currently in wheat stubble. The map unit describes the site as rarely flooded. Most agreed that the site was either rarely or possibly even very rarely flooded. Soil Survey Area: KS161 -- Riley County, Kansas
5-SAL -- Salina, Kansas
Pedon ID: S2014KS161503 Map Unit: 4350 -- Chase silty clay loam, rarely flooded
Pedon Note: This pedon description was classified as a Pachic Vertic Argiudoll which is a taxadjunct to the Chase series. It was felt that this Chase pedon would not have aquic conditions. It was also felt that it would not meet the requirements of oxyaquic (saturation for 20 or more consecutive days or 30 or more cumulative days) during normal years. The organoargillans that were described in the lower horizons were along old large root channels that were from before this field was farmed. Quad Name: Swede Creek, Kansas
