Soil water retention and conductivity plots

Description

Functions to display water retention curves and conductivity curves.

Usage

soil_retentionCurvePlot(
  soil,
  model = "SX",
  layer = 1,
  psi = seq(0, -6, by = -0.01),
  relative = TRUE,
  to = "SAT"
)

soil_conductivityCurvePlot(
  soil,
  model = "SX",
  layer = 1,
  psi = seq(0, -6, by = -0.01),
  relative = TRUE,
  to = "SAT",
  log = TRUE,
  mmol = TRUE
)

Arguments

soil	Initialized soil object (returned by function soil).
model	model Either 'SX' or 'VG' for Saxton's or Van Genuchten's water retention models; or 'both' to plot both retention models.
layer	Soil layer to be plotted.
psi	A numeric vector specifying a sequence of water potential values.
relative	Boolean flag to indicate that retention curve should be relative to field capacity or saturation.
to	Either 'SAT' (saturation) or 'FC' (field capacity).
log	Boolean to display the y-axis in logarithm units
mmol	Boolean flag to indicate that saturated conductivity units should be returned in mmol/m/s/MPa. If mmol = FALSE then units are cm/day.

Details

• soil_retentionCurvePlot() allows plotting the water retention curve of a given soil layer.

• soil_conductivityCurvePlot() allows plotting the conductivity curve of a given soil layer.

Value

An object of class ggplot.
