WebFiner-grained materials (e.g., silt and clay) tend to have greater porosity—some as high as 70%—than coarser materials (e.g., gravel). Primary porosity tends to be higher in well-sorted sediments compared to poorly sorted sediments, where there is a range of smaller particles to fill the spaces made by the larger particles. WebFeb 2, 2024 · Soil bulk density showed a positive and significant correlation with clay (r = 0.45) , indicating that clay, even in small proportion in these soils, can occupy the spaces between larger particles (silt and sand), decreasing the size of the macropore, with a consequent decrease in total porosity and an increase in bulk density, but with no …
