aConductivity was performed with one part soil to two parts water (volume to volume). The resulting values are not directly comparable to those derived from methods used by the Soil Conservation Service. However, relative differences in results remain (e.g., sandy areas have lower conductivity). Conductivity values for all samples (with the possible exception of #14) indicate conditions not harmful for crops (Dr. Carl White, Research Associate Professor, Biology Department, University of New Mexico, personal communication 2011).
bpH was performed with 1 part soil to 1 part 0.01 M CaCl2 (pH 5.53).
