Table 28 - Selected Chemical Laboratory Data
Data are laboratory measured. Pedons were sampled and analyzed using standard procedures detailed in USDA Soil Survey Investigations Report No. 42, Version 3.0, Jan 1996. Analyses were run on whole soil, < 2mm, unless otherwise noted in footnote.
Pedon numbers marked with # are series modal locations.

Method and method codes: Organic carbon (OC) by wet combustion using Walkley-Black modified acid-dichromate,
ferric sulfate titration (6A1c). Organic carbon analyses dated after Feb. 1998 are only by dry combustion
(6A2d). Reaction (pH) by 1:1 water dilution (8C1f). Cation-exchange capacity (CEC) by ammonium acetate,
pH 7.0, steam distillation (5A8b). Sodium adsorption ratio (SAR) (5E). Electrical conductivity (EC) by
saturation extract (8A3a). Carbonate as calcium carbonate (fraction less than 20mm) manometric measurement
(6E4).
