Measuring soil bulk density serves to assess soil compaction and porosity, making it essential for understanding soil health and suitability for plant growth. Bulk density is the mass of soil per unit volume, which reflects how compacted the soil is. High bulk density typically indicates heavier compaction, which can restrict root growth and decrease the soil's ability to hold air and water, ultimately impacting plant health and crop yields.

Conversely, lower bulk density often suggests that the soil has adequate porosity, fostering an environment where roots can expand, water can infiltrate, and air can circulate, all of which are vital for effective nutrient uptake. This assessment helps agronomists and farmers make informed decisions regarding soil management practices, such as tillage and the addition of organic matter to improve soil structure.
