A simple interface to the ROSETTA model for predicting hydraulic parameters from soil properties. The ROSETTA API was developed by Dr. Todd Skaggs (USDA-ARS) and links to the work of Zhang and Schaap, (2017). See the related tutorial for additional examples.

ROSETTA(
  x,
  vars,
  v = c("1", "2", "3"),
  include.sd = FALSE,
  chunkSize = 10000,
  conf = NULL
)

Arguments

x

a data.frame of required soil properties, may contain other columns, see details

vars

character vector of column names in x containing relevant soil property values, see details

v

ROSETTA model version number: '1', '2', or '3', see details and references.

include.sd

logical, include bootstrap standard deviation for estimated parameters

chunkSize

number of records per API call

conf

configuration passed to httr::POST() such as verbose().

Details

Soil properties supplied in x must be described, in order, via vars argument. The API does not use the names but column ordering must follow: sand, silt, clay, bulk density, volumetric water content at 33kPa (1/3 bar), and volumetric water content at 1500kPa (15 bar).

The ROSETTA model relies on a minimum of 3 soil properties, with increasing (expected) accuracy as additional properties are included:

  • required, sand, silt, clay: USDA soil texture separates (percentages) that sum to 100\

  • optional, bulk density (any moisture basis): mass per volume after accounting for >2mm fragments, units of gm/cm3

  • optional, volumetric water content at 33 kPa: roughly "field capacity" for most soils, units of cm^3/cm^3

  • optional, volumetric water content at 1500 kPa: roughly "permanent wilting point" for most plants, units of cm^3/cm^3

Column names not specified in vars are retained in the output.

Three versions of the ROSETTA model are available, selected using v = 1, v = 2, or v = 3.
