Pedotransfer function to generate soil/geol parameter from soil texture PTF

Description

Pedotransfer function to generate soil/geol parameter from soil texture PTF

Usage

PTF(
  x = t(matrix(c(33, 33, 2, 1.4), ncol = 5, nrow = 4)),
  topsoil = TRUE,
  xmin = c(0.1, 0.1, 0.8, 1.2)
)

Arguments

x	data.frame or matrix, column = c(Silt_perc, Clay_perc, OrganicMatter _perc, BulkDensity g/cm3)
topsoil	TRUE/FALSE, default = TRUE
xmin	Lower limitation of the value of c(Silt_perc, Clay_perc, OrganicMatter _perc, BulkDensity g/cm3)

Value

Hydraulic parameters, matrix

Examples

x=cbind(10,40, 1:20, 1.5)
y=PTF(x)
apply(y[,-1], 2, summary)
plot(x[,3], y[,2])
