Soil bulk density determination method
WebThe bulk density (BD, Mg m −3) was determined with the thermogravimetric method, on the basis of the ratio of the mass of soil dried at 105 °C to the initial volume of the soil (100 cm 3). In the following development of PTFs, their recalibration and validation, the mean BD value was applied.
