Calculating the density of loamy sandy soddy-podzolic soils from penetration resistance diagrams

The possibility for the calculation of the soil bulk density from two-dimensional penetration resistance diagrams drawn using a penetrometer during the vertical sounding of the soil has been discussed. A method has been proposed for calculating the bulk density of loamy sandy soddy-podzolic soils from the soil penetration test diagrams. The model for the calculation of the soil bulk density is based on the general physical concepts with the involvement of similarity theory methods. The adequacy and quality of the model have been studied statistically. The model has been found to be suitable for calculating the bulk density of loamy sandy and sandy podzolic soils.
