Abstract
This is soil texture data (% sand/silt/clay) for samples collected June-August, 2014, in References Areas 3 and 4. Samples were obtained by coring to depths of 100-200 cm (site dependent) with a bucket auger. Sampling occurred at fixed intervals, e.g. 0-20, 20-40, 40-60, 60-80, and 80-100 cm. Individual samples were uniquely identified by Reference Area, Transect Number, and Depth. Samples were transported to Duke in plastic bags where they were opened and allowed to air-dry for a minimum of 2 weeks. After air-drying, samples were passed multiple times through a #10 sieve (2-mm mesh) to separate soil from > 2-mm fraction. Obtaining pre-sieve bulk soil mass, and post-sieve >2-mm mass, allowed >2-mm mass fraction to be estimated. The < 2-mm fraction was transferred to paper bags for oven-drying at 40C for 48-72 hours. Texture was measured on the oven-dry sample using a standard method based on gravitational sedimentation. The lab SOP is available upon request.
