Explanation:
Detailed explanation-1: -Bulk density is an indicator of soil compaction. It is calculated as the dry weight of soil divided by its volume. This volume includes the volume of soil particles and the volume of pores among soil particles. Bulk density is typically expressed in g/cm3.
Detailed explanation-2: -The weighty subject of bulk density relates simply to the ratio of solids (i.e., sand, silt, and clay particles) to pore space (porosity) in a given sample of soil. Bulk density typically increases as the ratio of solids in a soil increases, and conversely decreases as the ratio of solids decreases.
