R: Effective Rooting Zone depth

ERDICM {GSIF}

R Documentation

Effective Rooting Zone depth

Description

Derive Effective Rooting Zone depth i.e. an effective depth suitable for plant growth. Usually minimum depth of soil out of three standard rooting depths: limiting soil properties, depth to water-stagnating layer and depth to bedrock.

Usage

ERDICM(UHDICM, LHDICM, minimum.LRI, DRAINFAO, BDRICM, 
    threshold.LRI=20, srd=150, drain.depths, smooth.LRI=TRUE)

Arguments

`UHDICM`	numeric; upper horizon depth in cm
`LHDICM`	numeric; lower horizon depth in cm
`minimum.LRI`	numeric; minimum Limiting Rootability index
`DRAINFAO`	factor; FAO drainage class e.g. `"V"`, `"P"`, `"I"`, `"M"`, `"W"`, `"S"`, `"E"`
`BDRICM`	numeric; depth to bedrock in cm
`threshold.LRI`	numeric; treshold index for LRI
`srd`	numeric; maximum depth of interest
`drain.depths`	data.frame; estimate effective rooting depth per drainage class (`DRAINFAO`)
`smooth.LRI`	logical; specify whether to smooth LRI values using splines

Value

Returns a vector of effective rooting depth in cm.
