Core Versus Nuclear Gauge Methods of Determining Soil Bulk Density and Moisture Content

and moisture content measurements were obt d using two nuclear gauge systo those obtained from soil cores. The soil wassee sandy loam, a Lakeland loyd clay, were free of organic matter and uni in mechanical composition. The ns developed for the nuclear hase of the study failed to predict bulk density and moisture content in the vali‘dation phase. T he test results indicate that if greater confidence is placed on the standard soil core determinations, then regression equations should be develo soil condition an8 ed for the nuclear gauges in each for each soil type.
