Soil water retention and conductivity plots

Source: R/soil_retentionCurvePlot.R
soil_retentionCurvePlot.Rd

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.

Value

An object of class ggplot.

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.
