Question

Importance of calculating field bulk density of soil

Answer 1

Soil bulk density is defined as the ratio of the mass of dry solids to the bulk volume of the soil occupied by those dry solids. Bulk density of the soil is an important site characterization parameter since it changes for a given soil.

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. ... Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).
