Mr. Amin Shavandi powder related to polymer or metal or composite. Find the attachment it includes all details of determination of density.
Bulk density is the weight of soil in a given volume. Soils with a bulk densityhigher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density.Bulk density measurements can be done if you suspect your soil is compacted or as part of fertiliser or irrigation management plans (see Bulk Density – On Farm Use) factsheet. To account for variability, it is useful to take several measurements at the same location over time and at different depths in the soil, for example at 10, 30 and 50 cm depths to look at both the surface soil and subsoil.
You did not indicate the type of powder density you may want to access, as there are several ― the following discussion may possibly be found of some help: https://www.researchgate.net/post/What_is_the_difference_between_bulk_density_tapped_density_and_true_density_of_a_food_product
