30.07.2011· Bulk density is defined as the mass of a bulk material divided by the volume occupied by that material. To understand this concept of bulk density, one must first understand what bulk materials are. Bulk materials are substances such as powders, precipitates, crystals or even gelatin materials. The basic property of bulk materials is that, the bulk materials have pockets of other materials

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher 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 can be used to calculate soil properties per unit area (e.g. kg/ha). Background. The soil bulk density (BD), also known as dry
