inline double calc_ptf_aimrun2009(double clay, double bulk_density, double organic_matter, double gmd)

Parameters¶

Name	Description
`clay`	Clay content, <2 um. (%)
`bulk_density`	Dry bulk density. (g/cm^3)
`organic_matter`	Organic matter content. (%)
`gmd`	Geometric mean diameter of texture. (mm)

Returns¶

Saturated hydraulic conductivity. (m/s)

Note

Sand and silt are not inputs to the selected final model.

Note

Applicability: Clayey rice soils with compacted subsoil.

Warning

The formula uses natural logarithms of all inputs.
