Query USDA-ARS ROSETTA Model API
Description
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.
Usage
ROSETTA(
x,
vars,
v = c("1", "2", "3"),
include.sd = FALSE,
chunkSize = 10000,
conf = NULL
)
Arguments
x |
a |
vars |
character vector of column names in |
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 |
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 percent
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
The Rosetta pedotransfer function predicts five parameters for the van Genuchten model of unsaturated soil hydraulic properties
theta_r : residual volumetric water content
theta_s : saturated volumetric water content
log10(alpha) : retention shape parameter
[log10(1/cm)]log10(npar) : retention shape parameter
log10(ksat) : saturated hydraulic conductivity
[log10(cm/d)]
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".
