Method synopsis

Hand auguring soil cores to saprolite at multiple sites across elevation gradient, followed by air-drying, sieving to <2mm, and grinding to fine powder for spectroscopic analysis.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — A molecular investigation of soil organic carbon composition across a subalpine catchment (2018), Soil Systems. Implementations in other papers (listed below) may differ.

1. Site selection and soil core collection
   Soil cores were collected by hand auguring to saprolite from four sites: Bradley Creek Meadow (BCM) at 2987m elevation, Bradley Creek Willow (BCW) at 2975m, Rock Creek Meadow (RCM) at 3466m, and Rock Creek Fen (RCF) at 3444m. One soil core was collected from each site.
   Quantities: 4 sites total, 1 core per site, depth increments chosen to reflect approximately 10-cm incrementsDuration: Not specifiedConditions: Field sampling conditions not specified
   Equipment: hand auger
2. Soil sample preparation
   Soil samples were aged, labeled, air-dried, sieved to collect <2 mm fractions, and ground to fine powder with agate mortar and pestle for all characterization experiments.
   Quantities: All soil samples processed to <2 mm fraction sizeDuration: Not specifiedConditions: Air-dried at ambient conditions
   Equipment: sieves, agate mortar and pestle
