Soil particle density (Dp) has been mainly determined using methods which measure solids volume by liquid displacement and its volumetric quantification. The volumetric measurement shows low precision, requires time for complete liquid drainage and is the longer lasting step. The objective of this paper was to substitute the volume displacement measurement step by weighing the volume displaced and to present an alternative method to measure the Dp. The Dp of 60 soil samples varying in texture and organic matter was determined by volumetric flask and modified volumetric flask, estimating exactness, precision and processing time. The Dp averages for both methods were similar, with the modified flask method presenting greater precision and smaller processing time.
