DOI: https://doi.org/10.2134/csa2019.64.0211 Interpretive Summary: Technical Abstract: Estimating soil texture is a fundamental skill used by scientists to classify soil based on the apparent grittiness, cohesiveness, and stickiness. While texture estimates from seasoned soil scientists are generally viewed as reliable, less is known the about the accuracy of novice soil scientists. New research in the Soil Science Society of America Journal summarizes soil texture estimates of scientists with a range of backgrounds, including a comprehensive analysis using the National Cooperative Soil Survey (NCSS) soil characterization database as well as seasonal data collectors working on rangeland inventory and assessment programs in the Western United States and in Namibia. These findings underscore the need for all scientists to practice hand texture skills against known samples and to calibrate for localized variability in soil texture. |
