Shockey, Matthew C.Stewart, Ryan D.Keim, Richard F.2021-12-052021-12-052021-10-190361-5995http://hdl.handle.net/10919/106842Methods to measure shrinkage curves typically either disturb natural aggregate structure or include difficult or slow volume measurement techniques. Additionally, most shrinkage curves are obtained by serial measurement of a few samples. We obtained shrinkage curves by collecting rapid, one-off measurements of volume and moisture content for each of 200 undisturbed peds extracted from a field soil, taking measurements as peds slowly dried in the laboratory. The large sample size increased robustness of the shrinkage curve parameter estimates to noise generated by this rapid measurement technique, but a much smaller sample would have resulted in similar parameter estimates.7 page(s)application/pdfenIn CopyrightSoil ScienceAgricultureBULK-DENSITYWATER-RETENTIONVOLUME CHANGECLAYCURVECLODS05 Environmental Sciences06 Biological Sciences07 Agricultural and Veterinary SciencesAgronomy & AgricultureArticle - Refereed2021-12-05https://doi.org/10.1002/saj2.20318856Stewart, Ryan [0000-0002-9700-0351]1435-0661
