Calculate the soil particle density using the Schjonnen model and return
This function determines the particle density of soil based on the content of clay, organic matter, and specific densities of organic matter, soil particles, and clay. It implements the Schjonnen model (referenced year or name of the paper).
Parameters
- clayarray-like
Soil clay content
- orgarray-like
Soil volumetric organic matter
- densorgfloat, optional
Density of organic matter [g/cm^3]. Default is 1.4 g/cm^3.
- denspartfloat, optional
Density of soil particles [g/cm^3]. Default is 2.65 g/cm^3.
- densclayfloat, optional
Density of clay particles [g/cm^3]. Default is 2.86 g/cm^3.
Returns
- pdarray-like
Soil particle density [g/cm^3].
