soilinfo.rosetta: Get ROSETTA soil parameters from a Texture Class vector

In paleolimbot/soilptf: Implements ROSETTA pedotransfer functions in R

Description

Get ROSETTA soil parameters from a Texture Class vector

Usage

soilinfo.rosetta(textureclass, delog = TRUE, ranges = FALSE)

Arguments

textureclass	A vector of texture classes (will be sanitized with texture.class)
delog	Pass TRUE to de-log the parameters that are log-ed (alpha and n) or ln-ed (Ks and K0)
ranges	Pass TRUE to return the min/max of one standard deviation in addition to the values. If delog=TRUE these will transformed accordingly, and therefore may not be symmetric around each value

Value

A data.frame with the same number of rows as length(textureclass), and the following columns:

theta_r

Residual water content (cm3/cm3)

theta_s

Saturated water content (cm3/cm3)

log_alpha

The (log10 of the) alpha parameter in the Mualem (1976) model (log 1/cm). Will be just alpha if delog=TRUE

log_n

The (log10 of the) n parameter in the Mualem (1976) model (log unitless). Will be just n if delog=TRUE

ln_Ks

The (natural log of the) saturated conductivity (ln cm/day), Will be just Ks if delog=TRUE

ln_K0

The (natural log of the) K0 conductivity (ln cm/day). Will be just Ks if delog=TRUE

L

The L parameter in the van Genuchten (1980) model for unsaturated hydraulic conductivity (unitless)

In addition, columns with the names above and suffixes "_min" and "_max" will be returned if ranges=TRUE.
