Descripción
Soil bulk density is an indicator of soil compaction and soil health and is an important factor to consider when assessing the physical behaviour of soils, as it affects infiltration, root depth and restrictions, available water capacity, and soil porosity. Soil porosity controls many soil properties and ecosystem services and is consequently one of the most important soil characteristics.
This method is applicable to the determination of soil bulk density using the cylinder method. The cylinder method is generally used to characterize the bulk density of an undisturbed soil sample having a volume of between 100 and 250 cm3.
