Determination INTRODUCTION ● Unlike bulk density, which considers the volume of both solids and pore space within the soil, particle density is the mass of soil particles per unit volume of the particles only ● Particle density is affected by the type and amount of soil textures (sand, silt, clay, and organic matter) that the soil is composed of

Coupled with bulk density, knowing a soil’s particle density will allow for calculating the soils porosity Determining these three parameters allows one to make conclusions about maximum water storage, infiltration and percolation rates, and tolerance to root penetration .

METHODS AND MATERIALS ● Particle density is determined from samples collected from 0-15, 15-30, 30-45 cm depths from both compacted and non-compacted soils ● The lab consists of putting a known weight of air-dried soil sample into a pycnometer or volumetric flask, reweighing, adding water and then gently boiling to remove air bubbles .
