Bulk density of soil
The mass of dry soil per unit volume of soil, including the air-filled pore space, in its natural structural state.
Также говорят: soil bulk density, soil compaction
Bulk density is a fundamental indicator of soil physical quality, reflecting the soil's compaction and pore space available for root growth and water movement. It is essential for determining the soil's suitability for cultivation and identifying potential constraints to crop development.
Agronomists monitor this parameter to decide when and where deep tillage or subsoiling is necessary to break up compacted layers. It is a critical metric for managing soil health, especially in fields subjected to frequent machinery traffic.
A common mistake is failing to account for compaction zones caused by heavy farm equipment. Generally, values exceeding the optimal range of 1.0 to 1.3 g/cm³ indicate significant physical limitations that may require immediate intervention to improve soil structure and porosity.
