Determining Particle Density in Dairy Manure Compost

Abstract

To accurately determine the bulk density of composted products, particle density must be precisely quantified. A submersion technique developed for use in soil science was adapted by utilizing hexane (a low density solvent) to facilitate particle submersion. Two composts were subjected to multiple treatments to determine the precision of the method. The inexpensive methods produced repeatable results that will aid compost producers in quantifying their products.
