DOI: 10.2136/sssaj2018.06.0217
Abstract: The average particle density (ρd) is a fundamental soil property, used for calculating the total porosity. Traditional ρd measurement by pycnometer method is tedious and time-consuming. In this study, visible–near-infrared (vis–NIR) spectroscopy and a simple… read more here.
