## Bulk Density Description:

The Property of granules, powders, and other "separated" solids, especially used in foodstuff, chemical substances, ingredients, allusion to mineral components, or any other masses of corpuscular or particulate matter are known as Bulk density.

We also can describe it by using the mass of many elements of the material alienated by using the total volume which is occupied by them. The combination of internal pore volume, particle volume and inter-particle void volume is known as total volume.

It is measured in ‘grams per millilitre (g/ml)’ while its international unit is ‘kilogram per cubic metre’ (1 g/ml = 1000 kg/m3) because this measurement is taken by using cylinders. We can also use ‘grams per cubic centimetre (g/cm3)’ for this measurement.

### Properties of Bulk Density:

• Bulk Density is the weight of loose material in a given volume of water.
• To calculate soil properties per unit area, we can use Bulk density.
• Grimy soils are extra susceptible to more bulk density.
• If the bulk density of Soils is gone more than 1.6 g/cm3, then it is conduced, to restrict root growth.
• With compaction, when the Bulk density increases, it tends to increase with depth.

### Important Calculations:

#### Soil volume:

Soil volume = ring volume
So if we want to calculate the volume of the ring we can use the following rules:
• Measure the height of the ring with the ruler in cm to the nearest mm.
• Measure the diameter of the ring and halve this value to get the radius.
“Ring volume (cm3) = 3.14 x r2 x ring height”

### Example:

“If the ring diameter = 7 cm, Ring height = 10 cm
so the Ring volume = 3.14 x 3.5 x 3.5 x 10 = 384.65 cm3”

#### Dry soil weight:

If you want to calculate the weight of dry soil you need to check out following rules:
• Weigh an ovenproof container in grams (W1).
• Carefully remove the all soil from the bag and put it into the container. Put it into the microwave for 10 minutes, or in a conventional oven at 105ºC for 2 hours.
• When the soil is dry weigh the sample on the scales (W2).
“Dry soil weight (g) = W2 – W1”

### Bulk density:

Usually the Bulk density is conveyed in megagrams per cubic metre (Mg/m3) but its other corresponding units of ‘g/cm3’ and ‘t/m3’ (1 Mg/m3 = 1 g/cm3 = 1 t/m3) also can be used
“Bulk density (g/cm3) = Dry soil weight (g) / Soil volume (cm3)”
