Estimate Rooting Depth Parameters

Estimates rooting depth parameters for forest objects following Cabon et al. (2018).

Usage

estimateRootingDepth(
  forest,
  soil,
  PET_summer,
  P_summer,
  SpParams,
  fillMissing = FALSE
)

estimateRootingDepthList(
  forestlist,
  soillist,
  PET_summer,
  P_summer,
  SpParams,
  fillMissing = FALSE
)

Arguments

forest: An object of class forest.
soil: An object of class soil or a data frame with soil parameters.
PET_summer: Average (climatic) potential evapotranspiration (mm) corresponding to summer months.
P_summer: Average (climatic) precipitation (mm) corresponding to summer months.
SpParams: A data frame with species parameters (see SpParamsMED).
fillMissing: A boolean flag to indicate that missing estimates should be filled with mean values.
forestlist: A list of objects of class forest.
soillist: A list with objects of class soil or data frames with soil parameters.

Value

Function estimateRootingDepth returns object of class forest with modified values for Z50 and Z95. Function estimateRootingDepthList returns a list of forest objects with modified root distribution parameters.

Details

If PET_summer or P_summer are of length one, their elements are repeated for all elements in forestlist. Similarly, if soillist is an object of class soil or a data frame with soil parameters, the same soil parameters are repeated for all elements in forestlist.
