inline Puckett1985PTFResult calc_ptf_puckett1985(double sand, double fine_sand, double clay, double bulk_density, double porosity)

Parameters¶

Name	Description
`sand`	Sand content, 0.05-2 mm. (%)
`fine_sand`	Fine sand content, 0.106-0.25 mm. (%)
`clay`	Clay content, <0.002 mm. (%)
`bulk_density`	Oven-dry bulk density. (Mg/m^3)
`porosity`	Porosity calculated from measured bulk and particle densities. (cm^3/cm^3)

Returns¶

A Puckett1985PTFResult value.

Note

The regressions were developed for soils with similar genesis and clay mineralogy.

Warning

Use outside Lower Coastal Plain Ultisols requires independent validation.
