Bulk Density

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).

bulk density of 3/4 stone

 · For gravel, the bulk density can be higher up to 130 lbs/cf as the voids are filled with sand and smaller (than 3/4") stone. We need to know the gradation of the gravel to answer this question (which has yet to have been asked. However, it is up to Mr. Guest to clarify this point and he seems to have stepped away.

2019-6-30 · Factors affecting bulk density 1. Pore space: Since bulk density relates to the combined volume of the solids and pore spaces, soils with high proportion of pore space to solids have lower bulk densities than those that are more compact and have less pore space. Consequently, any factor that influences soil pore space will affect bulk density. 2. Texture: …

Bulk Density of a Soil

2008-6-13 · 1. The clod method usually gives higher bulk density values than do other methods. One reason is that the clod method does not take the inter-clod spaces into account. A second reason is that the soil volume is the air-dry volume, which is likely to be slightly less than the volume of a field-moist sample used in other methods. 2.

The bulk density, then, is the dry weight of soil divided by the volume of soil: 1.33 g / 1 cm 3 = 1.33 g/cm 3. For practice, consider a box of undisturbed soil from the field. The box has dimensions of 2.5 cm by 10 cm by 10 cm. The volume of the box can be determined by multiplying the height of the box times its width and its depth.
